Former Punjab police inspector Naurang Singh along with three former cops surrendered in the court of chief judicial magistrate (CJM) here on Tuesday.
The four were wanted by police in connection with sensational abduction and murder of Bikramjit Singh, a convict lodged in the Amritsar central jail.
Bikramjit was kidnapped while undergoing treatment for a back problem at Guru Nanak Dev Hospital of Government Medical College on May 5.
The three other surrendered cops have been identified as Jagjit Singh, Gurpreet Singh and Lakhwinder Singh - all former head constables (HCs), who were dismissed from service on May 18 along with Naurang Singh for their alleged involvement in the case.
The kidnapping had created a hue and cry in the public and among political leaders, and even led to protests by kin of the victim. After facing severe criticism for tardy handling of the case, police hurriedly carried out investigations that revealed that Bikramjit died while in custody of his abductors, who later dumped his body into a canal near Roopnagar.
After their surrender, the CJM placed the four in custody of the Civil Lines police. They will be produced before the same court on Wednesday when the court will decide whether to remand them to police custody or send them to jail.
The surrender came nearly three months after Bikramjit was abducted and murdered. The accused were left with no option as their anticipatory bail pleas had been rejected both by the district and sessions court and the Punjab and Haryana high court.
After the kidnapping, the Civil Lines police had registered a case under sections 22,223 and 224 of the Indian Penal Code (IPC). Section 302 (murder) was added later after Bikramjit's death was confirmed during investigations.
Bikramjit, a resident of Algaon Kothi village in Tarn Taran district, along with four other relatives were undergoing 20 years' imprisonment in a 2002 case involving the murder of six members of a rival group near Bhikiwind. Political colour was added to the case as the murders took place during the assembly polls.
After his abduction on May 5, Bikramjit's elder brother Dalbir Singh had alleged that his brother was "abducted" at the instance of their rival party that wanted to avenge the 2002 murders. He alleged that Naurang assisted in the abduction.
With the surrender of Naurang and his three colleagues, all accused involved in the case have been arrested. Earlier, the cops had arrested Budhiraj Singh, Naunihal Singh, Jaspreet Singh and Kulbir Singh, all residents of Algaon Kothi. They were named in the complaint forwarded by Dalbir.
During the period of militancy, Naurang often courted controversies for his high handed approach in dealing with militants. This brought him close to some senior police officers, who never hesitated to protect him. A couple of year back, some assault rifles were seized from his possession, but the case was suppressed at the behest of higher ups.
