A 48 year old man remains in police custody and is being questioned in relation to the alleged theft of heritage artefacts and munitions dating back to the First and Second World Wars.

Herts Police have cordoned off part of Windmill Ave, to enable them to execute a search warrant.

The man was arrested at 8am today (Wednesday) on suspicion of theft from heritage and protected sites.

The Army has established the safety of munitions and other items and these are all historic, believed to date back to the historic conflicts.

As a safety precauction, Windmill Ave is closed to vehicles from its junction with Chiltern Road and four homes, either side of the property, have been evacuated.

Those residents affected have gone to stay with relatives.
