Four juveniles were arrested last night at Cornbrook Metrolink station suspicion of possession of offensive weapons and conspiracy to commit robbery.
Police believed that all four have links to local organised crime groups linked to a series of violent offences.
Police also seized three large knives and ballistic grade body armour.
Sergeant Andrew Dixon from GMP Transport Unit said: “This was an excellent recovery by our officers who are patrolling day and night across Greater Manchester’s Transport Network to detect and disrupt organised crime, ensuring commuters and residents are safe.
“We will continue to proactively target anyone suspected of carrying weapons. The risks that they poise to our communities mean that we will take a zero-tolerance approach, if you are caught carrying a knife, you will be arrested.
