Steve-O detained by police for jumping off London bridge

Steve-O’s latest stunt is now water under the London bridge.

The 49-year-old “Jackass” daredevil made a big splash Thursday by jumping off Tower Bridge into the River Thames — but authorities weren’t amused.

He was quickly detained by London police, reportedly spending most of the day in a cop car.

“I just got out of a cop car… they gave me a real talking to for my ‘Mary Poppins jump’ off the Tower Of London Bridge,” Steve-O wrote on the newly-launched Threads on Instagram.

In a video obtained by TMZ, Steve-O opens a Union Jack umbrella that matches his “I Love London” shirt and climbs onto the ledge of the famed bridge.

Steve-O claimed to TMZ that police explained to him that they fear his stunt may encourage people to make suicidal leaps from the bridge.

Steve-O is in England to film his third comedy special as he embarks on his “Bucket List” tour.

“We just opened up tickets for the late show on July 14 at the Hackney Empire. It’s the taping of my Bucket List. Be there,” he said into the camera in TMZ’s video before being shoved into a cop car.

This wasn’t the first stunt Steve-O completed during his time across the pond.

He claimed in his Instagram Story that he also jumped off a double-decker bus Thursday.

Steve-O rose to fame in 2000 alongside “Jackass” cast members Johnny Knoxville and Bam Margera. The MTV stunt series was short-lived, but it sparked several spin-offs, including “Wildboyz” and “Dr. Steve-O.”
