Armed police raided a house in Watford at the weekend after a man was arrested in connection with a firearms investigation.

An eyewitness said there were “armed police everywhere” as officers smashed through the door of the property in Cassio Road on Saturday afternoon.

In footage from the day, officers in helmets and carrying guns can be seen watching the street, while in another video, armed police appear to be searching inside a car.

Thames Valley Police have now confirmed they were there to search the home of Andi Cera, 23, who was arrested on Friday and later charged as part of an investigation into a firearms incident in Slough on January 12.

An attempted murder investigation was launched after reports of violent disorder between a group of men in Kaywood Close.

Mr Cera was charged with possession of an imitation firearm with intent to cause fear of violence, violent disorder, and production of a class B drug (cannabis).

He appeared at Reading Magistrates’ Court on Saturday and was remanded in custody for his next appearance at Reading Crown Court on May 7.
