A NATIONWIDE hunt began yesterday after a man and his 14-year-old stepdaughter disappeared - days after her mother mysteriously vanished.

Lisa Allen was last seen at school on Thursday and there are now fears for her safety.

Police believe she may be with stepfather Nicholas Allen, 30, who went missing from home in Acomb, near York, the same day.

Sergeant Ian Dyer, of York police, said officers believed they were in a white Ford Galaxy vehicle, registration X798 CAN.

Lisa's mother, Christine, who police say is thought to be suffering from depression, went missing on September 12. She was last heard from on Monday when she contacted a relative by phone.

Officers remain baffled as to exactly why the trio have disappeared, but believe they may have some "financial issues".

Details of the disappearances were yesterday circulated among police forces nationwide.

Sgt Dyer said it appeared that Lisa and Mr Allen had planned their disappearance, but confirmed that the police were "concerned for Lisa's welfare".

Lisa's grandmother, Pauline, who lives at the family home in Thoresby Road, said that she was sick with worry.

"Lisa told me she had school football practice at lunchtime but never came back," she said.

"I'm very concerned. I've not been able to sleep. I've got no idea what this is all about, but I believe Lisa has gone to be with her mum."

Police say Lisa is white, 5ft 1in, of proportionate build, with blue eyes, and blonde hair with strawberry highlights, which is usually tied back. She has a fair complexion, wears a brace and is well spoken.

Her mother is described as 5ft 4in, slim, with shoulder-length dark brown hair. She was wearing blue jeans, a grey jumper with a lion motif and a blue bodywarmer when she disappeared.

Mr Allen is 6ft 2in, slim, and was dressed smartly.

Sgt Dyer said: "We have got concerns for Lisa's welfare and would appeal for anyone with information to come forward."

Anyone with information about their whereabouts is asked to contact York police on (01904) 631321.
