SCENES of crime officers were called to Grimsby tonight after unconfirmed reports of an incident involving three men who may have been armed.
A white tent was erected by the specially trained officers in Castle Street as police officers stood guard outside a bookmakers shop on nearby Park Street.
The Humberside Police helicopter was also called and was seen searching overhead.
Local residents who do not wish to be named, said they were alerted to the incident by the sound of sirens at around 9pm.
They came out of their homes to see what they said were three men running from Park Street in the direction of Castle Street.
Two of the residents said they thought they saw they looked like a weapon, possibly a gun, although that has not been confirmed.
One woman said: "I was on my laptop and nearly dropped it after hearing an almighty loud bang – to me it sounded like a gun shot.
"And then after that I heard lots of sirens and the police arrived."
