Anti-social behaviour 'diverting PSNI resources'

A senior Police Service of Northern Ireland (PSNI) officer has said anti-social behaviour in Belfast is diverting resources from other serious crimes.

There have been ongoing problems involving groups of young people throughout the city.

Police believe alcohol and drugs are a factor, although they say anti-social behaviour has decreased overall.

BBC News NI reporter Richard Morgan joined a PSNI patrol to see and hear the issues they face on a weekly basis.
