Vancouver, British Columbia (CNN) -- Police are asking for public assistance in locating actor Andrew Koenig, who is best known for appearing in the 1980s sitcom "Growing Pains."

Koenig, 41, lives in Venice, California, but was visiting friends in Vancouver, police said in a statement Sunday. Friends last saw him on February 14. He was supposed to return home last Tuesday, and Vancouver police were notified Thursday that he had not arrived.

"Andrew has recently been despondent and his family and friends are concerned for his well-being," the police statement said.

Koenig was described as being 5 feet 5 inches tall and weighing 135 pounds, with brown shoulder-length hair and brown eyes, authorities said. Anyone with information on his whereabouts was asked to notify police.

Koenig appeared in 25 episodes of "Growing Pains" from 1985 to 1989, playing Richard "Boner" Stabone, according to the Internet Movie Database Web site. He also has appeared in episodes of several other TV shows.
