A 14-year-old girl armed with two kitchen knives has been arrested after a knifepoint robbery at Whitefield Metrolink stop.

At around 7.40pm yesterday a group of youths threatened a teenage boy with a knife before stealing some of his belongings, at the station in Stanley Road.

Officers rushed to the scene and arrested three teenagers, including the girl, on suspicion of robbery and drugs offences.

A statement from GMP Prestwich labelled the offences "unbelievable" and added: "This must stop."

In a further statement on Facebook, Greater Manchester Police's Bury South team said: "On arrival the offenders had left the scene, but whilst speaking to the victim he pointed out the offenders a short time later.

"Two male juveniles were arrested on suspicion of robbery, one female juvenile was arrested on suspicion of being involved in the robbery, possessing a bladed article and two further charges for police assault (spitting and biting).

"All the youths who were not involved with the robbery but were with the offenders were given the chance to leave the area. 

"One male refused to leave and was detained and searched, upon searching him officers found a large amount of cannabis, tablets and cash in his trendy man bag - subsequently arrested on suspicion of possession with intent to supply.

"They are all still enjoying our en-suite custody cells and I’m sure they’re parents will be proud! Know the law on carrying knives!"

The 14-year-old girl was arrested on suspicion of robbery, possession of a bladed article and two counts of police assault.

A 17-year-old boy was also arrested on suspicion of robbery and possession of drugs with intent to supply.

And a 15-year-old boy was arrested on suspicion of robbery.

Danny Vaughan, Head of Metrolink said: “Nobody should be subject to this type of attack on the Metrolink network and we’re pleased that Greater Manchester Police took such quick action in stopping the perpetrators. 

“Our TravelSafe Partnership has been set up to keep the travelling public safe and deter and prevent crime and anti-social behaviour on the network.

“We will continue to work closely with GMP to tackle such incidents and together we are committed to making transport safer for everyone.”

Correction: An early version of this story reported that four people had been arrested and the girl detained was aged 15. Police have since given the Bury Times updated information.
