The 20-year-old woman and a 14-year-old girl handed themselves into Tamworth police within hours of the surveillance footage being released online.

A third woman - dressed in black - is still wanted for questioning as part of the police investigation, but officers believe the public can help track her down.

Police went public with the investigation in a bid to track down three allegedly pictured damaging property at the skate park just after midnight on Wednesday.

Police will allege the 20-year-old and 14-year-old damaged tiles and fences at the skate park, on the corner of Peel and Macquarie streets, in Viaduct Park, in the early hours of Wednesday.

The 20-year-old woman was issued a notice to front Tamworth Local Court later this year for malicious damage.

The 14-year-old will be dealt with under the Young Offender's Act. But the police probe is still ongoing.

"A third female, pictured in black, is still outstanding and has not been identified by the other persons," Officer-in-charge of Tamworth, Chief Inspector Jeff Budd told the Leader on Thursday.

"Police are still looking for her.

"These two handed themselves in essentially, and we're looking for public assistance from anyone that knows the identity of that third female to come forward."

Chief Inspector Budd said the quick apprehension of the two suspects was a "huge win". He said the speedy investigation should serve as a warning for anyone that damages public property in and around the CBD, with council's eyes in the sky watching 24 hours a day.

"Oh definitely, it's a huge win for council with this state-of-the-art CCTV," he said.

"This is very clear; it's magnificent in terms of identification of persons at these locations."

Anyone with information on the identity of the third female is urged to contact Tamworth police on 6768 2999.
