The police booked some unidentified people on the charges of making threat calls to the Barnala deputy superintendent of police (DSP) on Friday.
A case has been registered under the Information and Technology (IT) Act, 2000, with the IT wing of the Sangrur police.
Barnala DSP Swaran Singh Khanna reported to the police that he received several calls on May 7 and May 25.
As per the FIR, the caller threatened the DSP with dire consequences for no apparent reason.
Sources in the department revealed that the police have not traced any suspect in this regard so far.
“We have not got any clues about the callers as the call details and contact addresses as per the mobile numbers have failed to give any positive results so far,” said a senior police officer.
Khanna was posted as DSP at Sangrur for several years and was transferred a few months ago. During his stint in Sangrur, he unearthed several gangs of criminals and robbers.
Repeated attempts to contact the DSP proved futile as his mobile phone was found switched off.
