Officers have arrested four men after police received an anonymous call regarding a possible sighting of a man with a gun.
Just before 12.30am on Tuesday, August 13, police received the call about the man who was spotted near popular Watford club, Pryzm.
Officers immediately attended the scene, searched the area and arrested four men, three 18 and one 19 and seized a firearm and a vehicle.
All four remain in custody at this time and three were arrested on suspicion of possession of a firearm in connection to the incident.
No one was injured as a result but detectives are appealing for witnesses and information.

Detective inspector Jason Finnegan, from the Watford Local Crime Unit, said: “We are working hard to unpick the circumstances around these events and I appreciate that news of this may be unsettling to the wider community, however at this stage we believe it was an isolated incident.
“Thanks to the person who bravely made the initial report, we were able to immediately locate the suspects and seize a weapon, so I would like to thank them for their actions.
“However since then we have made several attempts to contact that person, but the number they provided us is no longer connecting.
“Unfortunately they terminated the call before the member of staff in the force communications room had chance to record any further detail.
“Therefore we are very keen to speak to them, or anyone else who may have seen a man acting suspiciously in the area around Gaumont Approach yesterday evening, as we believe they will have vital information that could assist our enquiries.
“I would also like to speak anyone else who believes they have details that could prove useful to our investigation to please get in touch as soon as possible.”
