Armed police looking for a firearm carried out a search in St Albans yesterday afternoon.

Police were called at around 2.20pm following an alleged road rage incident on the M25 in which a gun was apparently seen.

The armed police unit and the police dog unit were deployed to track down the vehicle involved, and it was subsequently brought to a stand-still in Sandpit Lane by specialist officers.

Two people were detained while an extensive search of them and the car was carried out. No weapons were found.
