ARMED police brought Fleetwood to a standstill after it was feared a man was in a flat with a gun.
Fleetwood Market was forced to close as around 20 officers targeted the property above the Nuborns shop on Adelaide Street.
It came after reports from a member of the public that a man in the house could have access to firearms.
Following an hour-long stand-off with police, a 40-year-old man was arrested on suspicion of possessing an illegal firearm, assault and false imprisonment.
Witnesses described the swoop, which involved five police vehicles, dogs, trained officers and special negotiators as ‘dramatic’.
Cory Shipton of Norbreck owns a mobile phone shop on the market.
He said: “They had been waiting round the corner all day and there has been a CID car at the end of the street all day. The officers with two dogs went in first and then all the other went in – they had guns, big ones. It was definitely something very serious for all this.”
Ben Grisenthwaite, who works on the same stall, said: “Some police went round the back to get that covered and then the other all piled in.
“It didn’t take long. They brought a bloke out. No-one knew what it was all about.”
Police remained at the scene until the early hours of the evening and investigations are ongoing.
Supt Richard Spedding said: “We received reliable information that a 40-year-old male may have been in possession of an illegal firearm.
“The primary objective was the risk to the public so we want to eradicate that risk and arrest the member of public as soon as possible.
“There was quite a lot of police activity in and around the area as we dealt with the situation and our officers remained at the property while further investigations were carried out.”
Supt Spedding said he would like to thank the public for their assistance during the siege.
