He got involved with Neo Nazi's and they were financially abusing him, they also did something called cuckooing where they took over his flat and he would have some very nasty people staying there taking drugs, he also takes drugs. Crack and heroin. etc.
The police finally raided his flat and they found a large quantity of drugs and drug paraphernalia, also Neo Nazi paraphernalia. My son was also arrested but its worked out well as the police could obviously tell my son is backwards so they had an appropriate adult with him while they interviewed him, Then on release on bail social services safeguarding team were involved and they are supporting him. hopefully they move him into supported living where he can be looked after away from abuse. I hope they help him with his drug problems as well.
I just wanted to report back.
