Tim Sperry, who manages a bingo hall on Hucknall High Street, said his customers told him there was a man in the nearby snooker club with a gun:
Mr Sperry described the scene:
Basically, there's a guy in the snooker hall with a gun and he's said that the only way he'll come out is shooting.
So at the moment, there are about seven armed police stood outside the bingo hall in body armour, helmets and carrying sub machine guns and they're telling us to stay inside and lock the doors.
"We're fine in here, although it's a little bit surreal," he added.

Remains found in the garden of a house in a quiet cul-de-sac have the same distinctive feature that an elderly woman who used to live at the property had, police said.
The bodies of two people found buried in the garden are believed to be William Wycherley, who would now be 100, and his wife Patricia, 79.
The couple moved in to the semi-detached house in 2 Blenheim Close, Forest Town, Mansfield in 1987 but there has been no trace of them since 1998.
Patricia's maiden name was Moore it is believed she was born in Fulham, police said.
Nottinghamshire Police say they are confident the remains of two bodies found buried in a back garden are those of Patricia and William Wycherley who lived at the property in Forest Town, Mansfield, during the 1990s.
Nottinghamshire Police have confirmed they have now launched a double murder inquiry following the discovery of human remains found buried in a back garden at Forest Town, Mansfield.
Police officers are continuing investigations at a Mansfield home where human remains have been found.
Police were called to the house in Blenheim Close, Forest Town, Mansfield, on Friday after receiving a tip-off about a possible incident in the 1990s.
A couple who previously lived in the house, William and Patricia Wycherley, disappeared at around that time - but neighbours have said they simply thought the pair had emigrated.
Police believe the remains may hold the answer to the mystery of what exactly happened to the elderly couple, but say it could take weeks to formally identify the bodies.
Detective Chief Inspector Rob Griffin, who is leading the investigation, said:
Neither William nor Patricia was ever reported missing and we can find no evidence of either of them being alive or dead. The discovery in their former garden last week may be the reason why.
We have yet to formally identify the remains, and so cannot say with 100% certainty who we have found, but it's not a great leap to imagine it might be the Wycherleys.
