Hi Currently visiting parents. Dad just ran upstairs and attacked mum while she was asleep. He is calmed down now but keeps saying he wants her dead. He is sleeping in the lounge now but agitated and aggressive towards mum who does nothing but look after him. How long should this go on before we put him in home? Also what is the process? Shall I call the police? No other family as I am an only child and rest of family 100 miles away. Any advice would be appreciated.
