Tears for drugs tragedy girl

The 15-year-old died in hospital on Saturday morning after being rushed from lecturer Brian Dodgeon's home after a party.

Isobel, Mr Dodgeon's daughter Beatrice Hadjipateras, 14, and two boys took drugs which police believe might have belonged to the academic.

The 60-year-old was arrested on suspicion of possessing drugs and child abandonment and bailed until June.

Today, after tributes poured in for the schoolgirl on Facebook, youngsters gathered on a green in Chiswick, west London, where Isobel went to school.

It is believed Isobel, Beatrice and the two boys found the drugs, including ecstasy and ketamine, after the unsupervised party began.

The four were taken to hospital at about 4am after Isobel stopped breathing - but the three others were detained only for observation.

Neighbours reported the raucous party getting out of hand with groups of boys fighting.

Mr Dodgeon's employers at the University of London's Institute of Education, will meet tomorrow to discuss the situation.

Mr Dodgeon, a research fellow who studied subjects such as alcohol consumption patterns, was out of the house, in Kensington, with his partner Angela Hadjipateras on Friday night.

Police sources said officers have not ruled out also arresting her on suspicion of child abandonment.

Police released a statement from Isobel's family, saying: "Isobel's family and friends are devastated and heartbroken by her untimely death. We hope that if anything positive comes from this dreadful event, it is that others will make the right decisions to be safe and well in the future."
