domestic breach of the peace

[rhksmum]

Can anyone tell me what this is?
My friends ex husband has just been charged with this and is being kept in the police station until Tuesday, when he will go to court.
We are in Scotland if that makes any difference.

Thanks

see here

googling indicates that it's a breach of the peace related to a domestic incident

ie, a man comes home and finds he is locked out and kicks up a ruck

Thanks will let her know.
