A 17-year-old girl dealing with "personal issues" has gone missing from a secure unit in Renfrewshire.

Jordann Webb left the Good Shepherd Centre in Bishopton to go to a work placement in Greenock on Tuesday.

But after calling staff that afternoon to tell them she was visiting a friend, hasn't been seen since.

She is described as being white, 5ft 2 inches tall with a slim build and long brown hair.

She was last seen wearing black jeans, a grey Adidas hooded zipper and was carrying a pink Puma bag.

Police have been carrying out investigations to trace her.

Sergeant David Edington said: "We are becoming increasingly worried for Jordann who has not been seen now for four days.

"Jordann has been missing before, however never for this length of time.

"She has been dealing with some personal issues recently and this may have something to do with why she has not come home, however, whether or not this is the case, we need to make sure she is safe.

"We need to find her to make sure she is ok, so would appeal to anyone who may have seen her or has any information as to where she is, to contact police.

"We would also appeal to Jordann herself to get in touch."

Anyone with any information regarding Jordann's whereabouts should contact officers at Johnstone Police Station via 101, quoting incident number 3196 of Tuesday February 13.
