A Watertown state representative was arrested and charged with drunken driving after police say he struck a parked car and left the scene near the State House early this morning.

“I am a state rep,” John Lawn, a 56-year-old Watertown Democrat who represents the 10th Middlesex District in the Massachusetts Legislature, allegedly told a police officer at around 1:20 a.m. as the officer approached Lawn’s GMC Yukon SUV.

The vehicle, the officer noted in his report, appeared to be “leaning to one side” as it was parked on Bowdoin Street near the intersection with Beacon Street. The officer noted “extreme damage to the passenger side front wheel … turned to an extreme degree not consistent with normal vehicle operations.”

The officer also noted “a strong odor of an alcoholic beverage” coming from Lawn, and that his eyes were “glassy and bloodshot, and his speech was slurred.”

Lawn faces charges of operating a vehicle under the influence of liquor and leaving the scene of property damage. His driver’s license is also suspended for refusing to take a breathalyzer test.

The person who flagged the police down said that he saw the Yukon strike a parked Toyota Tundra pickup truck on Hancock Street before then blowing past multiple stop signs without stopping, according to the police report.

The police officers ordered Lawn to exit the vehicle and noted that “he had difficulty maintaining his balance” and dropped his license and a credit card on the ground. He told the officers that he was driving from an event at the State House, according to the police report.

Lawn then proceeded to bomb a field sobriety test, according to the police report. The report notes that Lawn continually failed to follow instructions and even stabilized himself using both the police officer conducting the tests and a fence post. Lawn then refused to submit to a breathalyzer test.

“You know what I’d rather do,” Lawn allegedly told the officer, “I want to take an Uber and go home.”

He was instead arrested, and he allegedly continued with drunken antics at the Nashua Street Jail.

According to the police report, officers there had to steady him as he walked and that he made a mess of a urine sample process. Lawn allegedly couldn’t figure out how to do the test, and when he finally peed into the cup, he allegedly then dumped it all into the toilet and handed the intake nurse the empty cup.

This is a developing story.
