'Initial reports suggested that a rumour about electric current leaking into the rainwater in the school triggered a stampede. Victims later revealed that the boys who came over to the school to give their examination tried to molest them, resulting in the mishap,' the police official added.

Some parents maintained that there have been incidents of boys harassing girls in the past as well.

According to hospital authorities, the medical reports have suggested there were no electrocution injuries and most girls had injuries in abdomen, chest and hands.

The All India Progressive Women's Association (AIPWA) and the All India Students' Association (AISA) held a protest at Jantar Mantar against the state of affairs in government-run girls schools in the capital.

Their activists burnt effigies of Sibal and Dikshit and shouted slogans against them.

'The Dikshit government as well as Sibal's ministry are directly and criminally guilty of the schoolgirls' deaths in a government school,' said AIPWA national secretary Kavita Krishnan.

Dikshit ordered an inquiry into the incident Thursday and the report is expected to be submitted in two-three days.
