UPDATED: Man beaten, robbed in Altadena

ALTADENA -- A man and woman beat and robbed a man Friday on Fair Oaks Avenue in Altadena, authorities said.
The incident was reported about 6:30 p.m. on Fair Oaks Avenue near Mendocino Street, Los Angeles County sheriff's Sgt. Mike Brandriff said.
A black woman in her 30s approached the victim, a man in his early 50s, and propositioned him for sex, Lt. Larry Landreth said.
A black man in his 50s then pushed the victim to the ground, causing him to strike his head, and punched him in the face, the lieutenant said.
As the injured man lied on the ground, he added, the woman reached into his pocket and stole his wallet.
The man and woman ran south on Fair Oaks Avenue and deputies searched the area with police dogs, but Landreth said the robbers were not found.
The victim suffered a broken nose, a large cut to his head and other injuries in the attack, Landreth said.
He was hospitalized but checked himself out before deputies could interview him at the hospital, officials said. The address and other information he left at the hospital did not appear to be valid.
