At around 7:10 pm Sussex Police received reports of shots being fired at a vehicle on Theaklen Drive in St Leonards in East Sussex.
Shortly afterwards, a report was received of a man possessing a firearm in nearby Churchill Court on Stonehouse Drive.
Armed units responded to the scenes of both incidents, assisted by specialist officers from neighbouring forces and the National Police Air Service helicopter (NPAS), to minimise the threat to the public.
A Local resident who captured this video said “On Stonehouse drive, armed police looking for someone/weapon?..”
No injuries have been reported.
A man was arrested in connection with the incident and a firearm has been seized. He remains in police custody whilst investigations continue,
Chief Inspector Jayantha Mendis-Gunasekera, of Hastings Command, said: “Due to the nature of the reports we received, it was imperative that we responded accordingly, and this included calling upon our neighbouring forces for support.
“Thankfully, no injuries were reported and we can confirm it is not being treated as a terror-related incident.
“I appreciate this will have been of significant concern to the local community, who can expect to see an increased police presence in the area in the meantime.
“There were a number of people in the area around that time and I am urging anyone who saw what happened to please come forward. You can report it online or via 101, quoting Operation Beaumont.
“I would like to commend the officers involved for their swift support, and also extend my thanks to the public for their patience and understanding as our enquiries into this fast-moving investigation continue.”
