Thieves are targeting mobile phone owners in bars in Preston city centre, police have claimed.
The warning follows a number of thefts of high value phones from people in the city centre where their owners are distracted and often under the influence of alcohol.
Last weekend, Lancashire Police recorded three separate reports of phones being stolen from MACs Bar on Friargate.
PCSO Stephen Connolly urged revellers to be vigilant.
He said: “Keep a close eye on your possessions, especially whilst out socialising in busy pubs and clubs as there are increased opportunities for the thieves to target people and steal personal belongings.”
On Saturday night, a student reported an iPhone 4 being taken from her shoulder bag whilst in MACs Bar on Friargate with another iPhone 4 and a Blackberry curve taken in the venue on the same night.
An iPhone 4 was also taken from a bag in Baluga on Church Street on Sunday.
