Two teenagers were detained after a stash of drugs and weapons were uncovered on a police raid.
The haul, which included a knuckle duster and an air pistol, was seized when officers stormed a house in Johnson Street, St Helens, just before 6pm on Wednesday, September 30.
Officers also uncovered cannabis, suspected cocaine and a number of phones, all of which were seized pending further investigation.
Two teenagers, aged 19 and 17, were found inside the property and 'immediately detained'.
Inspector Rob Budden said: "This warrant is a result of the community getting in touch with us and letting us know who they suspect to be involved in criminal activity and where it's taking place.
"Those involved in drug crime plague our neighbourhoods in both St Helens and across Merseyside and we won't idly stand by and watch them cause fear in our community."

He added: "We know that the majority of people appreciate our efforts in taking these harmful substances out of circulation and acknowledge the fact that drug crime almost certainly can lead to more serious violence, something we'll do everything in our power to avoid.
"Hopefully these two young men have been given a chance to re-evaluate their choices and by intervening now, we have stopped two more from committing other offences."
