The home invasion robbery happened about 11 a.m. at a house on a private road in the 11400 block of Laurelcrest Road, said Los Angeles police Sgt. Warren Jones of the North Hollywood Station.

The victim, Bob Romans, is a former physician who lives alone, KNBC reported.

A man in his 30s walked up to Romans, who was sitting outside his home, asked for directions, and then forced the elderly man into his home, Jones said.

"He started talking to him and the next thing he knew the guy pushed him into the garage and he fell on the concrete, and then he dragged him inside and shut the door," his daughter, Lynn Takacs, said.

He beat Romans, bound him to a chair with wire, ransacked the house, took his cell phone and credit cards, then knocked him over the head with a wine bottle when he left, KNBC reported.

Romans eventually worked himself free and called police, the TV station reported. His daughter said Roman had craftily held his hands wide apart when the robber tied him up so that he could easily free himself when the man left.

He was transported to Providence Saint Joseph's Medical Center in Burbank, where he required 40 stitches, according to KNBC.
