Three masked men walked into the Pacific Shores Inn on 4802 Mission Boulevard and shoved a gun in the clerk's face, demanding money, police said. Two of the men were armed with handguns.
The hotel clerk was unable to open the safe, so the gunmen took his cell phone. One of the gunmen then hit the clerk on the head with his gun. The robbers took an unknown amount of money from the clerk and two other people who were in the hotel lobby.
The clerk was taken to Scripps La Jolla Hospital to treat his head injuries. No one else was hurt in the holdup.
Police said the robbers may be the same men wanted in a string of violent robberies in San Diego over the last month.
The Yakyudori restaurant in Kearny Mesa was robbed in a similar fashion last week. In that incident, one of the gunmen also pistol-whipped an employee before taking off with money.
