RESIDENTS of a flat block in Durrington were evacuated on Saturday night, after a man threatened to cause an explosion inside the building.
Police attended the flats at Winterbourne Close, Durrington, at around 8.40pm, after a man reported missing from a mental health facility was located alone inside a flat.
He refused to let officers in and threatened to harm them and himself.
Negotiators spent several hours trying to persuade the man to open the door, but he made further threats to cause an explosion.
Other flats at the property were evacuated as a precaution, and fire and ambulance crews stood by.
Police then forced entry to the flat.
A 51-year-old man was arrested on suspicion of affray. He was later released on police bail but was detained for hospital treatment under the Mental Health Act.
No one was hurt.
