A 14-year-old girl was sexually assaulted in Masterton's Colombo Rd on Saturday night, police say.
The attack comes just over a month after another sexually motivated attack, in Queen Elizabeth Park.
The girl told police she was walking alone near the Colombo Rd bridge about 9.30pm and was confronted by a man who pushed her to the ground and assaulted her.
Detective Sergeant Tracey Calder said police were still trying to identify the attacker, who was unknown to the girl.
Wairarapa CIB have conducted a scene examination and the girl will be interviewed in the next few days.
