Tejpal Singh, Harminder Singh, Satinder Singh, T S Dhillon and others were booked under IPC section 434 (prevention of damage to public property act, 1984), they said.
The move came after the father of the soldier, who was killed in 2001 during an anti-militancy operation in Poonch, expressed distraught over the alleged repeated defacement of plaques.
Ajit Singh, father of Lt Gurwinder Singh, had also approached the district authorities and Police Commissioner saying that he cannot bear this insult to his son.
"My son who died more than 10 years ago is being insulted repeatedly. I am too old to continue this struggle now," Singh said.
"From last 10 years my son is being insulted which is unacceptable to me. The culprits must be booked as anti-nationals," Singh said.
