Ever want to take a cop car for a joyride? A San Francisco man did just that, complete with screaming siren and flashing lights.

Wayne H. Reagan, 48, allegedly stole a San Francisco sheriff's deputy's cruiser last Wednesday afternoon after a woman flagged down the deputy.

The deputy had parked the car and taken the ignition key, sheriff's spokeswoman Eileen Hirst told KTVU-TV, but Reagan somehow managed to get the unlocked green-and-white cruiser started.

As the deputy and the woman stood talking, Reagan, out on parole for an unspecified offense, allegedly drove right by.

For the next 20 minutes, he drove around the Potrero Hill (search) neighborhood, getting the attention of passers-by with the noise and lights.

Finally, he cruised in front of the Bayview station of the San Francisco Police Department (search). Officers, already alerted by the suddenly pedestrian sheriff's deputy, quickly set up a roadblock and snared Reagan.

He was arrested on suspicion of grand theft, evading police, resisting arrest and theft of an official car, and was given a psychiatric evaluation.

"We will be reviewing this incident to make sure it's the last time it happens," said Hirst.
