A teenager has pleaded guilty to an armed robbery in Birmingham.

The 17-year-old boy, who cannot be named for legal reasons, arranged to meet the victim in Lozells on May 11.

Arranging the visit via Facebook Marketplace, the teenage boy produced what the victim believed was a gun and took £600 in cash.

After an investigation, West Midlands Police officers from the Neighbourhood Crime Team identified the offender and he was arrested.

During the arrest, a zombie knife was also found in his possession.

The teenager was charged with multiple offences and remanded to court.

On Tuesday, June 3, at Birmingham Youth Court, he pleaded guilty to possession of an imitation firearm with intent to cause fear of violence, robbery, and possession of an offensive weapon.

He will be sentenced next month.

A West Midlands Police spokesperson said: “Tackling robbery remains one of our force’s top priorities and we are committed to identifying and taking action against offenders who inflict harm on our communities.”

In September, West Midlands Police urged people to hand over zombie-style knives and machetes after it became illegal to own.

Insp Colin Gallier previously said: “We’ve seen the tragic consequences of someone carrying a knife, gun or other weapon too many times.

“They can have a devastating and life-changing impact on so many people.

“We have dedicated teams working day in, day out, to keep taking weapons off the streets.”

Individuals can dispose of the weapons in safe, surrender bins in Birmingham.
