It is amusing that Majithia is backing a notorious gangster's statement and raising questions over Punjab CM's statement, he said.
"My question to Majithia is that you are going by the claims of Goldy Brar about his detention but doubting the statement made by CM Bhagwant Mann," Kang said.
Earlier, Punjab Congress chief Amrinder Singh Raja Warring had also asked the Punjab Director General of Police to clear air on the detention of Brar.
Shubhdeep Singh Sidhu, popularly known as Sidhu Moosewala, was shot dead in Punjab's Mansa district on May 29.
Satinderjeet Singh alias Goldy Brar, a member of the Lawrence Bishnoi gang, claimed responsibility for the singer's brutal murder. A red corner notice, which allows the arrest and detention of a fugitive abroad, was issued against him.
Moosewala's murder was in retaliation to youth Akali leader Vicky Middukhera's killing that took place last year.
