Police have expressed concern over night-time street patrols by a loyalist community group in east Belfast.

The group, Action for Community Transformation (ACT), told the BBC the aim of the patrols is to prevent crime and deter anti-social behaviour.

ACT is involved in community work. It has set up groups of residents to walk around their estates, watching for burglars and "suspicious activity".
