A police spokesman said "gun and gang activities will not be tolerated".
Four people were arrested for possession of a significant quantity of amphetamine and a number of drugs paraphernalia was seized. One person was arrested for possession with intent to supply cannabis.
Those arrested were for drugs and firearms offences
A property was repossessed and boarded up by Knowsley Housing Trust and a pit bull dog was seized. Police arrested six people for offences including possession of controlled drugs, drink driving, assault and sexual assault and seized four vehicles for no insurance.
Anti-crime leaflets were distributed to neighbouring homes.
Supt Martin Andrew, from Merseyside Police, said: "In partnership with our communities we are sending out a clear message that drug, gun and gang activities will not be tolerated."
