The former landlord of a problematic Visitacion Valley home has been accused of the vicious beating of a tenant and shocking two other people with a Taser in an earlier incident, police said.
On Wednesday, Bo En Liu, 35, of San Francisco was booked on charges of assault with a deadly weapon after he brought at least five thugs and a shovel to carry out a revenge smack-down at the two-unit property at 4150 San Bruno Ave., according to Ingleside Police Station officers.
Cops began searching for Liu soon after finding the tenant at his home “covered in blood” and riddled with gashes on his head and face. The 32-year-old, whom police have not named, is expected to survive.
An upstairs neighbor, whom police declined to identify, told officers Liu and his buddies “looked very intimidating” when they confronted the tenant Wednesday afternoon.
The neighbor did not see the fight, but heard “a loud pop that sounded like a gunshot,” police said. She called for help after finding the tenant bloody on the ground. There was a pool of blood near a broken shovel, police said.
One thug might have used a retractable baton, cops said.
Liu allegedly returned to the property, which had been foreclosed upon a week earlier, to exact revenge on the tenant following a Dec. 29 spat.
The tenant intervened in a fight Liu was having with the upstairs neighbor, police said. In that fight, Liu had used a stun gun on the neighbor’s boyfriend and her brother, according to cops.
The 32-year-old downstairs tenant grappled with Liu and “wound up rolling down a flight of stairs with him,” according to an officer at the Ingleside station.
Officers said they have had a history of trouble with Liu’s property. There have been several permit issues and violations.
“We were trying to get the city attorney involved to try and shut him down,” an Ingleside officer said. “It’s been a problem in the district for a while.”
A real estate firm that had listed the property called it “not for the faint of heart” and in need of extensive remodeling.
Liu was arrested after a police sergeant obtained his cell phone number and called him. Liu told the sergeant he would meet him at a Starbucks, but turned himself in at the Ingleside station.
Leo Muro, 43, also was arrested in connection with the attack. Muro joined Liu in the beating, police said. The other suspects remain at large.
