Police are continuing their search for anyone who may have crossed paths with a woman who was sexually assaulted as she walked home after concert.
Police said they were trying to piece together the 48-year-old victim's movements after she left a performance at the Lincoln Event Centre in Selwyn, central Canterbury, last Saturday evening.
In particular, they wanted to speak to a woman with pink and blonde hair and a man in a cowboy hat.
They also wanted to speak to a woman who helped the victim on the night, staying with her after the attack until a family member picked her up.
The victim left the Selwyn Sounds concert at 6.30pm and was sexually assaulted in the vicinity of North Belt and West Belt before 7.10pm, said Detective Senior Sergeant Scott Anderson.
During the attack she lost a fine gold chain bracelet with a heart-shaped gold locket. The locket has a small diamond on one side and a keyhole on the other.
"A middle-aged woman helped the victim on the corner of North Belt and James St outside the Lincoln Primary School, opposite the church. This lady stayed with the victim until she was collected by a family member," Anderson said.
Police would also like to speak to a man in a cowboy hat who was with a woman described as having pink and blonde hair, on the sports fields outside the concert.
In earlier appeals, police asked to speak to a man and woman seen having an argument while walking along the street from the direction of the Famous Grouse, in the Liffy Pl/North Belt area about 9pm.
These people or anyone who knows them can call police on (03) 363 4700 or Crimestoppers 0800 555 111
