The CBI has questioned AICC General Secretary, KC Venugopal, in a sexual assault case filed by the accused in the solar scam.
The senior Congress leader was questioned at the agency office here, sources said.
Venugopal allegedly sexually assaulted the woman at Rose House, the official residence of former Minister AP Anilkumar.
The alleged assault took place when the complainant reached Anilkumar's residence seeking favour in a tourism-related project. The complainant had reportedly handed over digital evidence to the investigators to buttress her case.
The state Crime Branch probed the case initially before the CBI took over the investigation during the previous LDF regime.
The Congress had then dubbed it a 'politically motivated' move claiming the CPM-led State government could not find anything against its leaders.
In May, a CBI team visited the Cliff House, the official residence of Kerala's Chief Minister, for gathering evidence in the allegation against former Chief Minister Oommen Chandy.
The complainant had also alleged that Chandy had harassed her at the Cliff House in September, 2012.
The Crime Branch had registered six FIRs accusing Venugopal, Chandy, Hibi Eden, Adoor Prakash and BJP leader A P Abdulla Kutty in the case.
