New Delhi: In mounting trouble for sacked Delhi minister Sandeep Kumar, the woman who purportedly figured in an 'objectionable' CD with him, has accused him of allegedly raping her after spiking her drink, following which Kumar on Saturday surrendered at the DCP's office in the national capital.

The woman filed a complaint against Kumar at Sultanpuri police station alleging that she was raped by him after being offered a spiked drink, official sources said.

She alleged in her complaint that the CD was made after Kumar became a minister.

The woman claimed she had gone to meet Kumar for his help in getting a ration card. She was asked to wait at the minister's office and then offered a cold drink which was allegedly spiked, the sources said.

After she lost consciousness, she was allegedly raped. The woman claimed she did not know a CD had been made, they said.

Sanjay Singh, Joint Commissioner (Northern range), said that the victim's statement was being recorded.

A case under IPC section 376 (rape) has been registered, police said. Meanwhile, Sandeep Kumar reached the office of DCP (outer) to surrender.

Delhi Chief Minister Arvind Kejriwal tweeted that Kumar should be given "exemplary punishment" if the allegations turn out to be true.

If woman's allegations are correct, this is v serious. Strongest exemplary punishment shud be given to Sandeep https://t.co/P9TZuxJf1I — Arvind Kejriwal (@ArvindKejriwal) September 3, 2016
