Police and family hold concerns for the welfare of 14 year old Ava Louise Baker.

Ava left her Mount Stuart residence sometime last night between 11pm and the early hours of this morning.

Ava was last seen wearing a green hoodie with white writing on the sleeves and possibly a Taroona High School jacket. She likely is carrying a blue Sportsgirl gym bag with her.

She has dyed brown hair and may be wearing a beanie. She is approximately 170cm tall, blue eyes with pale white skin and a slim-average build.

Ava is likely to be in the greater Hobart area.

We would urge anyone who has had contact or seen Ava to contact Tasmania Police on 131 444 or Crime Stoppers anonymously on 1800 333 000 or online at crimestopperstas.com.au
