An elderly man has been charged with performing an indecent act on a child after members of the public pulled the boy from the man's car outside a Hamilton park.
Police have not ruled out the possibility of other victims.
The 69-year-old Hamilton man was arrested and charged after the incident on Friday, which police said took place during a touch rugby tournament at Tauhara Park. He appeared in the Hamilton District Court on Saturday and Monday over the alleged incident involving a 12-year-old boy.
Detective Sergeant Carl Moon of the Hamilton CIB said two workers at the Rototuna park witnessed concerning behaviour between the man and boy in a black Honda Civic hatchback car in an adjoining carpark. "Fortunately for the child they took the appropriate step of removing him from the car and contacted us."
He said detectives had a large amount of information to work through and police were not ruling out that there could be other victims.
