Addressing a press conference here, Shashi Kant further alleged some prominent ruling party leaders had prevented the concerned authorities from carrying out a raid at the house of an Akali leader who was "involved" in the drug racket.
"I have sent a list of over 100 names of influential people involved in the drug trafficking to the government. It included names of some ruling party members," said the former police officer.
In Chandigarh, the SAD denied the allegations saying it was a "cheap publicity stunt of a frustrated individual".
In a statement, SAD General Secretary Mahesh Inder Singh Grewal said Kant nursed a grouse against the SAD-BJP government for not fulfilling his ambition of becoming the DGP of the state.
Grewal said if Kant had any evidence of wrongdoings by any politician in Punjab, he should have recorded his findings in files.
