A WOMAN in a cocktail dress and high heels sparked a four-hour stand-off with armed police - after brandishing a fake rifle in a leafy suburban street.

Terrified neighbours took cover in their homes as armed cops swooped on the quiet street after Emma Ryan went on a rampage, shooting at windows with an imitation ball-bearing gun while dressed for a night out.

Ryan, 36, barricaded herself inside and refused to surrender after police surrounded the property during the terrifying stand-off in Grimsby, Lincs.

She denied possessing an imitation firearm - an airgun - with intent to cause fear of violence, but was convicted after a trial.

Cops, ambulances, helicopters and trained negotiators were called to the dramatic scene on October 8 after Ryan's bizarre stunt.

She was sentenced to six months in prison at Grimsby Crown Court.

Temporary Detective Constable Tom Kelly said: "I hope she is ashamed of her actions and that the sentence acts as a deterrent to anyone else behaving in such an irresponsible way."
