Arcadia police are investigating a recent rash of thefts at 24 Fitness, some from secured lockers. In one instance, a man had his keys lifted from his locker and his car stolen.
"The numbers are not particularly high, but what catches the eye of both our staff and the public are clusters of crimes," Sgt. Tom LeVeque said.
In September alone, the gym, located at 125 First Street, logged eight thefts and one auto burglary. In November, the gym logged five thefts and two auto burglaries. For all of 2012, there was a total of 22 thefts, 21 auto burglaries and one auto theft.
The thieves primarily targeted phones and wallets left unattended near the basketball court, LeVeque said, though in several cases, thieves forced open lockers secured with padlocks.
Police say they have been working with 24 Hour Fitness staff to curtail the thefts and find whomever may be behind them.
"Detectives met with both management and loss prevention staff back in October," LeVeque said. "The [24 Hour Fitness] staff was receptive and assisted us with the investigations; however, no workable information was developed sufficient to make arrests."
Representatives from 24 Fitness could not be reached for comment.
