Cars were searched and problematic homes were investigated as police stepped up their presence in Blackpool.
Officers were sent out on patrol in the town centre as warrants were issued and legal highs were seized from two shops.
Four wanted people were arrested for a variety of reasons, including failing to appear in court for animal cruelty offences and three breaches of suspended sentences.
Police also stopped 41 cars in the town centre and Talbot ward, and joined Lancashire Fire and Rescue Service and Blackpool Council’s Trading Standards team to visit problematic homes.
The visits cracked down on rogue landlords who are breaching fire safety laws and making their homes unsafe for tenants in Blackpool’s Talbot ward.
Neighbourhood policing officer Sgt Matt Plummer led the day of action.
He said: “It went really well because we have had town centre businesses coming up to us and telling us how good it has been and residents telling us about organised crime groups.
“There’s a lot of problems being caused for us and we can’t deal with them, but by taking the fire service and Trading Standards along with us they can tackle them.”
Shoppers in the town centre said they felt safer knowing the police were increasing their presence in the resort.
Carolinne Thornborough , 40, of Furness Avenue, Grange Park, said: “It does make me feel safer the police are checking this all out.
“I have three young babies and find it a really good idea to have more police on the streets.”
