Specialist police negotiators have been called in to deal with a stand-off in a Plymouth street.

Several police units, including officers in riot gear, have been called to Thomas Lane, off Diamond Avenue, in Lipson.

A police spokesman said one man has made threats to harm and officers and negotiators are at the scene in an attempt to find a peaceful resolution.

An ambulance has also been at the scene, though the street remains open.
