Sussex Police say they are greatly concerned for the welfare of 15-year-old Brighton schoolgirl Shaina Mack who is missing from home and who may be in the company of an older man.
Shaina was last seen at 12.30pm on Wednesday and reported missing at 3.30am today (Thursday November 23).
It is thought she may have got into a taxi in Old Steine with an unknown older man, possibly called Ace, with the intention of going to an hotel.
Shaina is described as white, 5ft 7in, of proportionate build, with shoulder length dark brown hair. She has fixed braces on her teeth.
Anyone seeing Shaina, knowing where she may be or having any other information that may assist in finding her is asked to contact police online or phone 101. In an emergency or if Shaina is in danger, call 999.
