Call him the Mad Slapper.

Cops this morning arrested a man they say has slapped, punched and pushed three women and one man, unprovoked, near City Hall and, yes, LAPD headquarters downtown.

[Update at 1:14 p.m.]: The LAPD says a victim ruled out Moran as her assailant, and now they're looking for another alleged slapper on the loose. From City News Service:

One victim, a woman who was accosted on Jan. 11, ``clearly eliminated'' Moran as the suspect, however, Vernon said. Her assailant was described as ... 5 feet 10 inches tall, ``thin, but not too thin,'' who wore dirty blue jeans. Anyone with information on the case was urged to call Crime Stoppers, (800) 222-TIPS.
