LUCKNOW: Uttar Pradesh Chief Minister Yogi Adityanath on Friday said some people arrested for alleged involvement in supplying illegal codeine-based cough syrup have links to the Samajwadi Party.

"Everyone knows that every 'mafia' group has ties with the Samajwadi Party," Adityanath told reporters ahead of the beginning of the Winter session of the UP assembly.

The chief minister said the Legislative Assembly will not likely see any business on Friday due to the sudden death of an MLA. But the government will respond to any questions on the matter in the legislative council and if it is raised outside the House, he said.

"However, initial investigation have revealed that some of the men arrested by the STF (special task force) or UP Police have links to the Samajwadi Party. The involvement of Samajwadi Party, which is already notorious and has a tarnished reputation, will also come to light since a state-level SIT is monitoring the entire case, and officers from the UP Police and the FSDA are part of it," Adityanath said.

Samajwadi Party president Akhilesh Yadav on Thursday alleged that a massive scam involving the illegal supply of codeine-based cough syrups running into thousands of crores originated in Uttar Pradesh and accused the BJP government of shielding those involved.
