Kevin Yates also had guns, knives and a crossbow in his home

The concern for welfare visit took place at 3.15am and the suspicious items were taken away from the scene.

Firefighters, police and the Army's bomb disposal team then carried out a search of the property.

A cordon was set up on Hayes Lane at the junction of Wimborne Road. Nearby properties were also temporarily evacuated.

Following the incident, Detective Inspector Wayne Seymour, of Bournemouth CID, said: “I would like to thank all those residents and members of the public who were affected while the emergency services dealt with this incident.
