A team of the Assam Police went to Congress leader Pawan Khera’s home in Delhi on Tuesday to question him in connection with allegations he made about Assam Chief Minister Himanta Biswa Sarma and his family, PTI reported.

Khera was not at home when the police arrived, and the authorities searched the house, PTI quoted Assam Police Assistant Commissioner Debojit Nath as saying.

Nath added that electronic devices and “incriminating material” were seized from Khera’s home during the search, The Hindu reported. He did not disclose what the material was.

The police officer said that efforts were underway to locate the Congress leader, the newspaper reported.

Sarma, meanwhile, claimed that Khera had “run away” to Hyderabad in Congress-ruled Telangana.

On Sunday, Khera claimed that he had documentary evidence that showed that the chief minister’s wife Riniki Bhuyan Sarma holds passports of the United Arab Emirates, Egypt, and Antigua and Barbuda. Himanta Biswa Sarma and his wife refuted the allegations.

On Monday, Sarma alleged that the documents cited by the Congress had been supplied by a Pakistani social media group. He had added that his wife had filed a first information report against Khera and others.

He had also claimed that the Congress had used details from a passport that had been allegedly lost. This document, he claimed, had been uploaded to the Pakistani social media group. “They photoshopped it,” he said at a press conference.

The case against the Congress leader has been registered at the Crime Branch Police Station in Guwahati, The Hindu reported.
