Police have arrested three people in connection to a rash of auto thefts at South Bay gyms.
The suspects -- identified by police as Anthony Roberts, Richard Higgerson and Colby Worsham -- are accused of stealing cars while victims were getting a work out.
Undercover San Jose Police Sgt. Ken Davis said in the last month, seven cars have been stolen from five different gyms. The gyms hit by the crimes are mostly in South San Jose, Davis said.
In another case, investigators said Worsham, who described as the ring leader in the auto theft operation, stole a car from the parking lot of the Oakridge Mall.
Inside the car police said Worsham found mail with a home address. Police said he stole a car from that home as well.
"They are all working together," Davis said, adding more arrests are expected in the case. "They were difficult to find due to the fact that they are transients."
Police said surveillance pictures taken inside the South Valley Family YMCA helped crack the case.
Carole Ruvalcaba, a YMCA employee, said two men walked into the gym on May 3 -- one distracted the front desk attendant, while the other headed to the locker room.
"Right away our staff knew something was odd," Ruvalcaba said.
By the time YMCA staff realized what was going on, both men had left in a stolen car with keys they took from the locker room.
"It's pretty bold for someone to do what they're doing," Davis said.
YMCA members on Monday were being warned to keep valuables out of the car and to lock keys while they work out.
