The teenage daughter of former Manchester City star Antoine Sibierski has been found dead in her apartment.

The body of Sibylle Sibierski, 18, was discovered by police when they forced their way into the property in Altrincham.

Police do not believe there are any suspicious circumstances.

Tributes to Sibylle - a nightclub promoter and former pupil of St Bede's School in Manchester and Cheadle and Marple Sixth Form College – were flooding in to the social networking site Facebook today.

Shocked friends set up a special tribute site which gathered 100 members within half an hour.

Pal Rachel Kirkham wrote: “I can't believe you are gone...I don't know what to say or do. Not a day will go by where I won't think about you Sibylle.”

Miss Sibierski had returned to the luxury apartment in Altrincham, after a night out on Sunday.

A relative, concerned about her welfare, then phoned police on Monday afternoon.

They arrived at the apartment but there was no response to their calls.

When police went to the apartment there was still no response and officers broke through the door to find Miss Sibierski's body inside.

Mr Sibierski - who played 92 games for Manchester City and 33 for Wigan Athletic during a glittering Premiership career - was too upset to talk when contacted by the M.E.N at his Cheshire home.

The striker, 35, retired after being released by Wigan at the end of last season.

His daughter had been promoting club nights at Manchester venues including Lounge 31 in Shudehill.

She described herself on Facebook as; “Cute, lovely, nice, naughty, cheeky, love my friends, love my family and in love with an amazing guy.”

In the early hours of Saturday she told friends on the social networking site: “Had a very good evening, Heart & Soul was good and I love A very, very much :) xx.”

A spokesman for Greater Manchester Police said police were called to an apartment in Altrincham at 5.40pm on Monday "following reports of concerns over the welfare of a woman."

The spokesman added: "Officers attended, forced entry and the body of an 18-year-old woman was discovered. The case has been passed to the coroner."
