An attack on four young women in Flaxmere is the fourth in Hawke's Bay since October and police are urging parents to teach children what they should do if confronted by offenders.
Hastings police hope the public can provide information on the latest attack on four women aged between 15 to 18, at Flaxmere Park on Sunday.
The girls were walking through the park about 8.30pm when they were approached by three men.
Police said the men told the girls they were squash pickers and were described as dark skinned, one of them being extremely tall.
Two of the girls were then pulled behind nearby bushes by two of the men and indecently assaulted. A member of the public went to the girls' aid and the men ran off in the direction of Dover Rd.
Anyone with information can call the Hastings police station on 873 0500 or Crimestoppers on 0800 555 111.
A 17-year-old girl was walking home from a friend's house in Pirimai on Thursday, January 31, when she was followed by a teenage boy on a bike and sexually assaulted.
In November, a 17-year-old girl was indecently assaulted near public toilets off Maadi Rd in Onekawa, Napier, and, in October, an 11-year-old girl was sexually assaulted by a man aged about 20 on the green belt along Georges Drive, Napier.
