A "beeping" noise heard coming from inside a bin has prompted police to close a road near a prison.

Officers were called to Edinburgh Road in the vicinity of HMP Perth on Thursday morning.

A passer-by reported hearing the "beeping" coming from a bin and alerted police.

Officers at the scene then shut off a section of the road between HMP Perth and Marshall Place.

A Police Scotland spokeswoman said: "Officers are attending in relation to a suspicious incident."
