How do I prove this?

(As far as the police are concerned, it doesn't make a difference as to whether its sound or video, but since it has been investigated by other authorities already, and "turned down" you'd need more).

I really feel for you, you must miss him a lot.

After all the discussion above, I think your only way forward is very hard, but it's to try and reconcile with mum and other grandma.

For his sake.

Let some time pass first: if mum and grandma are unresponsive it may be possible to approach Social Services (not quite clear from above exactly how much they were involved) to try and "Broker peace". -or even the school?

Meanwhile do the ordinary things: cards, presents for Christmas at a low level. of course it may not work, but best option?

Why is it only supervised access?

in what way does she hit him ?
are you in england.

Madgran77 Because he committed a crime and spent 8 months in Prison for it, (Sorry, i'm not allowed to give more details than that).

welbeck Yes I am in England. She slaps him so hard that she has left Hand Prints and Bruises on his Skin, and has on many occasions slapped him so hard she has caused him to lose his balance and fall over, causing further injury as he falls because he then
(1) banged his head on a table, (causing a small cut on his scalp),
(2) fell down the stairs, (causing extensive bruising on his hand, arm, and back),
(3) banged into a Radiator, (causing him to injure his shoulder),
(4) went face first into a Door Frame, (causing him to split his lip)
And these are just a few examples off the top of my head, there have been many more times that the slaps knocked him off balance resulting in secondary injuries as he fell over due to the force of the slap.

Call the |NSPCC?

Madgran77 I already suggested NSPCC and included their free phone number further back.

but he has already been interviewed by a MAST person, so it's pointless suggesting NSPCC/SS etc.
can you afford to engage a solicitor.
but realistically, you have to accept that if he were to be removed from their care, he would probably be placed with foster carers, or placed in a children's home, rather than with you.
do you have a history of involvement/caring with him.
it does sound strange that the professionals have no concerns, and also his father.
can you suggest why that might be.

How could all those injuries be unnoticed or discounted?

Why would more evidence be needed for police, just because some people have rejected it?
Surely the police can make their own decision about that?

Wouldn't hybrid1000 have a chance to get custody at least after some time of assessment?

There was a gran on here a few years ago whose grandson was in care because of a similar situation. It took her a long time but she did get custody of him in the end.

OP, have you tried approaching your local MP.

welbeck
No, I can't afford a Solicitor right now.

But I do have a History of caring for him, both my Grandson and his Mum lived with me for the first 4 years of his life due to his Mum having Mental Health Issues.

As for why the Professionals have no concerns, your guess is as good as mine, especially since MAST told me that they believed my Grandson and were trying to get enough evidence to be able to do something about it.

His Father on the other hand, is fully aware that they are hitting his Son, but he is simply choosing to ignore the problem, Mum and other Grandma told him that the other Grandma "Hit him once and has regretted it ever since", and even though I have told him that this is not the case and have proof that they are lying, he is choosing to believe them.

welbeck No I haven't approached my MP yet, though someone did suggest that to me a few days ago, I have been trying to negotiate via a third person with my Son and his ex Partner as a first step, but that is getting me nowhere.

Do you really think my MP could help me?

Perhaps your son fears being seen as a troublemaker and creating more problems for himself?
Trying to get him involved doesn't seem a very hopeful strategy.

Why not consult your MP? I don't know if they can help but it can't harm to ask, as you've done here.

FarNorth The injuries haven't gone unnoticed, but whenever anyone asks her how he got his injuries she always says that he is very clumsy and tripped or fell, and if he tries to tell anyone what really happened she will call him a liar, I have evidence of her doing this, the incident I mentioned before when he banged into the Radiator injuring his shoulder after being slapped, (on that occasion it was his other Grandma who had slapped him), that happened during a Video Call with me, but his Mum claimed that Grandma was "nowhere near him when he fell", and that "she did not hurt him", even though he can clearly be heard on the Video Recording saying that Grandma caused him to fall and hurt himself.
And unfortunately they always seem to believe her explanation.

FarNorth Yes, I think I need to go and see my MP, like you said, I don't know if he would be able to help, but if I don't ask I won't know, it's worth a shot.

Sorry missed that

Great minds think alike Madgran77. They will chat through your worries at least.

See a solicitor ad go for grandparents rights!!

I’d advise contacting your MP. Contacting as many people as possible as there have been so many dreadful cases where authorities have refused when grans have had concerns they may take notice. You should not be stopped from seeing your grandson as it will be detrimental to him as well as upsetting for you. You have my sympathy as you must be so concerned. Good luck.
