(KTLA) – A 50-year-old Los Angeles man who appeared in “Game of Thrones” was arrested last week after detectives said he was engaging in “online sexually explicit communication” with a minor victim who lived in another state. Now, investigators are looking for other possible victims.

Joseph Gatt of Los Angeles was arrested on Wednesday, April 6, after authorities served a search warrant at his home in Beverly Grove.

LAPD’s Internet Crimes Against Children Task Force began investigating Gatt after they received a tip that he was engaged in sexually explicit communication with the minor victim.

Gatt also had an outstanding felony warrant for a similar crime involving communication with a minor, police said.

Gatt, who was born and raised in London, played Thenn Warg in “Game of Thrones,” according to his IMDB page. Other acting credits include the live-action “Dumbo,” “Star Trek Into the Darkness” and “Thor.”
