Fears are growing for a 15-year-old British girl who has not contacted her family for three days.

According to a desperate online appeal by her parents, Olivia has been missing since Saturday evening.

Her family believe she is with a 21-year-old man who is said to be her ‘boyfriend’ – but claim he denies knowing her whereabouts.

The appeal by her mother reads: ‘Olivia has been missing since Saturday evening. She got a lift to malaga with a friend where she said she was meeting other friends and staying the night at friend’s house. We of course had no issue with this.

‘But she did not arrive at her friend’s house. Despite her friend trying to contact her. It is believed she has a boyfriend who is 21 and lives in Alora.

‘We assume she is there with him despite us calling him and him denying it. Olivia has done this before but never this long and this time we have heard nothing since Saturday evening when she messaged she had a low battery and was on her way to her friend’s and would message when she was there.’

Olivia lives in Comares and was last seen in Malaga in the Santa Barbara area, the appeal said, adding that she has connections to Alora and Velez-Malaga.

Olivia is approximately 1.65m tall and weighs around 65kg. She has blonde hair with a distinctive red stripe on one side.

The teen is described as having blue eyes and a slim build and speaks Spanish and English.

She was last seen wearing a pink top, black trousers, black body warmer, black and white NIke trainers and a pink Nike bumbag.

The appeal added: ‘She is 15 years old, vulnerable and it is now the second day she has not had her medication.’
