Som Lal was called in by police for interrogation in connection with three cases registered against him on December 28, said a senior police officer.
Presumably fearing arrest after interrogation, he jumped off the police station building, the senior officer said.
The policemen, fearing that action might be taken against them for the death of a man while in custody, dumped his body in a park, he said.
However, the matter reached the ACP (Model Town) and he reported the matter to the DCP (Northwest) Milind Mahadeo Dumbere.
They have been suspended and legal action has been initiated in the matter. Strict administrative and legal action will be taken against the erring policemen, he added.
DCP (Northwest) Milind Dumbere confirmed that five policemen have been suspended.
