Witnesses are being urged to contact police after two popular Blackpool venues were targeted by thieves and vandals.
Staff at Grange Youth centre, on Grange Park, discovered the centre had been burgled when they were called to deactivate the alarm and found 20 windows had been smashed.
Police said the vandals broke into the Dingle Avenue venue at 3am on Saturday.
The smashed windows caused more than £500 of damage. The vandals wandered through the building setting off the alarm sensors before running off empty handed, officers said.
Police are also appealing for information about a raid on Christ King Social Club, on Chepstow Road, Grange Park.
Thieves climbed over the garden fence to gain access to the church grounds connected to the social club on Thursday.
It is thought one of the gang had stolen a set of keys from the church earlier in the day and the key was used to let themselves in through a fire exit around 1.15am.
Once inside the gang ransacked the premises, helping themselves to bottles of vodka and whiskey, as well as £100 in loose change found behind the bar.
Officers are now trawling CCTV footage from both venues. A Lancashire police spokesman said: “These break-ins have caused a large amount of damage with costly consequences and we are very keen to trace the people responsible.
“The second break-in appears to have been a pre-planned. I appeal to anyone who has any information to call police on 101.”
