UPDATE: Holly Whalan has been located, police confirmed on Monday night.

A mother says she is “extremely worried” for the safety of her missing teenage daughter after the girl was allegedly taken across state borders.

Kahlia Whalan claimed people trying to contact her daughter Holly, 14, were being blocked and the teenager’s Facebook page had been deactivated since she was last seen on Sunday.

NSW Police said Holly was last seen about 12.15pm on Sunday at High St, Warialda – a town in the North West Slopes region, about 60km inland from Inverell.

“Police and family have concerns due to her age,” NSW Police said in a statement on Monday.

“Investigations indicate Holly may be in Woodridge, QLD, about 11.50pm last night.

“Police believe she may be travelling in either a 2015 blue Mitsubishi Lancer – QLD registration 741JD9 or a 2008 silver Audi A3 – bearing QLD registration 344GJ6 Qld and she may be in the company of two men, aged 22 and 24.”

Woodridge is located in the City of Logan, south of Brisbane and about five hours’ drive from Holly’s home town of Warialda.

Her mother published a desperate plea on social media for information about Holly’s whereabouts on Sunday night.

“The police are searching for her, she is 14 years old, anyone who tries to contact her is blocked immediately, her Facebook has been deactivated,” she wrote.

“We are extremely worried for her safety, please help us bring our baby home, if you know something do the right thing and tell us immediately.”

News.com.au has contacted Ms Whalan for comment.

She also shared CCTV footage of two cars – one blue and the other silver – which appear to match the models NSW Police described in its statement.

It is unclear whether these vehicles were the ones identified by investigators.

Holly is described as being of caucasian appearance, about 160cm tall, with shoulder length brown hair and brown eyes.

She was last seen wearing a white crop top and black and white tights.
