How can my Grandson aged 36 get some help.

I am a Grandma with a 36yr old grandson, who was diagnosed with Aspergers when he was 20 yrs old.  He is really struggling. He now has no support.  Is there anywhere that he can go during the day like day centre or get some sort of support worker..   He is spending his days just riding on buses. but someone complained about him to the bus driver and he was put off the bus.  He is now frightened to go on the bus now.   We live on the south coast
