A man seen waving a handgun in a North Shore street sparked a major police incident this morning.
Armed officers attended Cromwell Road shortly before 9am and arrested a 26-year-old man from Blackpool - outside a house - on suspicion of possessing a firearm.
CCTV seen by The Gazette shows a man brandishing what appears to be a gun and using the weapon to strike the window of a nearby car.
Armed officers, police dogs, and officers from the tactical support unit were called to the scene.
Police confirmed a 'small gun' had been found.
The force was not immediately able to say what sort of handgun was recovered, but a picture shared by officers appeared to show a realistic looking Crosman pistol.
Crosman makes gas-powdered BB guns.
Westminster Primary Academy in nearby Claremont Road was put on lock-down, a spokesman for the Fylde Coast Academy Trust (FCAT) confirmed.
The school has around 350 pupils, who were kept in class unaware of what was unfolding outside while staff locked the front door.
Around 40 minutes later, police gave the all clear.
"FCAT has emergency plans in place in all its schools, which teams practice on a regular basis, which include lock-down scenarios," John Topping from FCAT said.
The arrested man remains in custody.
In a statement, Lancashire Police said: "Enquiries are on-going and there is no on-going threat to the wider community."
