A special branch officer of the state intelligence was caught red-handed while clicking photos of documents during the BJP's national executive meeting held in Hyderabad.
The said documents were kept on a table when the incident was reported.
The documents contained details of the party's resolution and also details on the upcoming meetings at the national executive meeting.
BJP leaders, including Union Minister G Kishan Reddy, confirmed the incident.
"There is no secrecy in our party. Our party is a democratic party. It is not a family party. Whoever came was illegal. We don't do the security, it was the police department who gave it. When the PM comes, the karyakartas are not allowed and the police takes over everything," said Mr Reddy.
He further said that the party has nothing to hide.
"Whoever comes, we give them information. There is nothing to hide. If KCR wants, we can give the resolution to him, but taking the resolution from an ongoing meeting is wrong," he said, referring to Telangana Chief Minister K Chandrashekhar Rao, who is popularly known as KCR.
Union Minister Piyush Goyal also reacted to the incident and said that the government believes in transparency.
"Our government believes in transparency, we ourselves put everything on the website, so whoever wants to come can come. There is no secret activity. We are working for the welfare of the people," said Mr Goyal.
The BJP national executive meeting moved to its second day on Sunday. The key focus remained on Prime Minister Narendra Modi's speech and the party's political resolution that was expected to be passed unanimously.
The political resolution moved by Home Minister Amit Shah at the Hyderabad National Executive meeting also affirmed that in the next two-three decades India will emerge as a "world leader".
The meeting was attended by the top leadership of the party, including Prime Minister Narendra Modi, BJP national president JP Nadda, Union Home Minister Amit Shah, Chief Ministers of 19 states and other senior BJP leaders at the Hyderabad International Convention Centre.
