TMZ reports that the Los Angeles City Fire Department is upset with Steve-O for faking seizures with three of his friends at a West Hollywood coffee shop, which caused police and paramedics to respond to a 911 call.

The video (which you can find here) shows the group faking spasms and frothing at the mouth while customers call 911.

Since Steve-O and his friends didn’t call 911, they can’t be prosecuted for making a false report to the authorities. The people who made the call can’t either, as they did it thinking it was a real emergency. Captain Jamie Moore said he’s contacting Steve-O, his lawyer and publicist to tell them their prank threatened the lives of others. The ambulance or fire truck could have had an accident or someone who didn’t get an ambulance in time could have died.

Moore said: “The L.A. Fire Dept. frowns on his action that impacted public safety.“

Steve-O agrees that his stunt should be illegal, but he’s not taking responsibility.

He added: “This ‘seizure prank’ wasn’t my idea or my operation, and I agree it was a real stinker.“

He said the stunt provided an “invaluable service by exposing a glaring shortcoming in the laws.”
