Police are stepping up the search for a missing teenager in northern Tasmania who hasn't been seen or heard from in 10 days.
Shyanne-Lee Tatnell, 14, was last seen near Henry Street, in Launceston, near the North Esk River, at about 8.30pm on Sunday, April 30.
Police, including specialist units, are returning to the river today for another search for the teenager and any of her belongings.
"On Thursday specialist police officers from search and rescue, our dive squad, and the Westpac rescue helicopter will also be deployed to search the North Esk River," Inspector Craig Fox said.
Investigators also want to speak to anyone who was driving a vehicle on Henry Street, Launceston, in the vicinity of the North Esk River between 8pm and 9pm on April 30.
"These drivers could be potential witnesses of Shyanne-Lee's last known movements, whether they think they saw anything or not," Fox said.
"We have CCTV images of some vehicles in the area at the time, and while the image quality isn't great we're hoping it may prompt drivers' memories."
"If you were driving through this location in either direction at this time, please make contact with police."
"One small piece of information could be all we need to locate her."
Shyanne-Lee is described as being approximately 160cm tall, slim build with blonde hair.
At the time she was last seen, she was wearing a cream hooded jumper with dark coloured writing on the chest and shoulder area. She was also wearing bike shorts.
