On January 29, 2010, the CBI had submitted the first closure report which was rejected by the court of Special CBI Judge Darshan Singh. He had ordered a reinvestigation on January 26, 2011.

The multi-crore scam hit the headlines in 2006, when the CBI registered a case against senior Punjab Police officers for alleged embezzlement, in connivance with wireless suppliers, between 2000 and 2003. The case was transferred to the investigating agency on May 30, 2006, following directions from the Punjab and Haryana High Court.

The FIR registered by CBI named the then DGP-cum-commandant (Punjab Homeguards) K K Attri, former ADGP (vigilance) Izhar Alam, former IG (crime) G D Pandey, former DIG (intelligence) R P Singh and former SP (Lokpal) Malvinder Singh Sidhu, besides former ADGP D R Bhatti, former ADGP S C Jain and IG R C Prasad, who has since passed away. All the officers were booked under the Prevention of Corruption Act.

The officers were serving in the Punjab Police’s communication and wireless (C&W) wing, when they allegedly paid a substantial amount of money for low grade wireless instruments, which did not meet specifications laid down by Directorate of Coordination (police wireless) set up by the Ministry of Home Affairs.

The officers had allegedly inflated bills to the tune of Rs 2.77 crore, when they had allegedly paid only Rs 18 lakh to 19 lakh for the wireless instruments. Two local lawyers had moved the High Court alleging large scale irregularities.
