A 21-year-old man was arrested Tuesday morning for allegedly assaulting at least four people at a Santa Rosa medical center, then stripping off his clothes and fleeing naked down the street in a drug-fueled tirade.

Joshua Fajardo, of Santa Rosa, was taken into police custody after being struck by a car near the medical site on the 500 block of West College Avenue, then continuing to run in the buff until an officer deployed a Taser, according to police. Officers cuffed Fajardo while he was incapacitated and transported him to Sonoma County Jail.

Three victims were treated for head injuries, none of which was considered life-threatening, police said.

The incident began around 9:45 a.m. at a home on the 1500 block of Ridley Avenue, where residents reported that Fajardo began acting bizarrely and violently under the influence of multiple drugs, including methamphetamine and LSD, according to police.

He reportedly punched his 39-year-old housemate in the head, then grabbed a kitchen knife and threatened others in the home before leaving.

Shortly afterward, a car was reported to have crashed into a water main nearby causing a large plume of water to shoot from a broken pipe, according to police. The crash was traced to Fajardo’s car.

After that, Fajardo was reported to have entered the medical center, first attacking a man in the waiting room, then chasing a woman who tried to escape through a receptionist’s window.

He attacked at least two others as he went through various rooms, banging on doors, police said, before a 71-year-old female employee at the medical center fought back, grabbing him by the testicles.

“Her actions were effective and he left the room,” a police press release said.

Fajardo was ultimately detained nearby on Zuur Street. He was arrested on suspicion of four counts of felony assault, elder abuse, two counts of misdemeanor assault, driving under the influence of alcohol, brandishing a weapon and violation of probation.
