The bureau had on July 7 issued a look-out notice against him in view of reports indicating that he might flee the country.
Besides, a letter was also submitted to the office of the Director General of Police (Administration) in which Singh said that he had no plans to visit abroad.
Singh is required for questioning in connection with an FIR registered at Flying Squad police station, Vigilance Bureau.
The FIR pertains to allegations against dismissed Inspector Inderjit Singh, then posted in Tarn Taran, and Raj Jit Singh, who was SSP there.
According to the FIR, some alleged drug smugglers had managed to get a clean chit in chemical examination of certain drugs seized from them as a result of the complicity of the lab staff, a police spokesman had said.
It was further alleged that Inspector Inderjit, on receiving a tip-off, had called the said lab staff for questioning and instead of arresting the main accused, had, in consultation with Singh, made him an approver in the case.
There are allegations that money was exchanged in the process, police said.
Singh is at present posted as commandant 4th battalion Mohali since his transfer out of Moga as SSP on July 2.
Notably, the Punjab and Haryana High Court had last year ordered constitution of a special investigation team led by DGP Sidhharth Chattopadhyay to probe the role of Singh and Inderjit in another drug trafficking case.
The SIT was formed after Singh moved the high court seeking directions to not hand over the case to Special Task Force chief H S Sidhu, claiming that he had strong apprehensions that he would be falsely implicated by Sidhu.
Chattopadhyay had submitted the report in the case to the high court in May this year.
