Bathinda, May 25 -- A retired Punjab police sub-inspector Angrez Singh, who was one of the investigating officers and a key witness in the Sidhu Moose Wala murder case, died due to an illness on Friday. He was under treatment at a private hospital in Ludhiana. Singh was the station house officer (SHO) of Mansa Sadar police station when the Congress leader and famed Punjabi singer was shot dead at Jawaharke village in Mansa on May 29, 2022. Being among the first police personnel to reach the crime scene in his beat, Angrez was among the key persons to give testimony in the crime. Sources privy to the prosecution say it is premature to conclude that Angrez's death will hamper the case in the court. Angrez had an important place for the prosecution, but the case was not entirely dependent upon his testimony, said sources. "It was a long investigation where several police personnel had roles. Angrez had not been keeping well for quite some time, and he was not able to appear before a trial court in Mansa in the last two hearings. Moosewala's father, Balkaur Singh, and another cop, Sukhpal Singh, are other witnesses in the case and their testimony would play an important role in the case," said a source. A Mansa court will hear the matter on July 4....
