Police said: “Two male victims in their mid-20s reported that there had been an unsuccessful attempt to steal the car that they were driving in.

“A subsequent search did not recover a firearm or other residue.”

They said the next night police were called at the same time to the Heath Street area to reports of the robbery of a vehicle, a blue Rover hatchback.

A spokesman said: “The two male victims, aged 18 and 27, told police that the suspects threatened them with a gun and a knife.”

Detectives believe the same pair of suspects are responsible for both attacks.

The victims described the suspects as two black males, aged between 20 and 30 years, wearing dark coloured jogging bottoms and hooded tops. Witnesses should call police on 101 or 0800 555 111.

One resident, who asked not to be identified, said: “It’s so bad. I was woken up with police cars everywhere. I’ve told the council for years something bad will happen one day near this restaurant.”

Controversial milkshake bar Tinseltown has been at the centre of a battle by residents to limit its hours and have it closed down.

People who live nearby claim that unruly customers leave a trail of litter, flout parking restrictions and wake children up in the early hours,

When the Ham&High contacted Tinseltown to ask about the incidents a manager said he was unaware of the raids.

Police said there are no arrests to date and enquiries continue.

Anyone with information about the incidents should call police on 101 or 0800 555 111
