Director of the Park Abhay Kumar today said instructions have been issued to disallow securitymen with arms to enter the zoo, and added that "the rule has to be adhered to."
"The probe has revealed that the guards at the gate of the zoo didn't muster courage to stop securitymen accompanying Prasad during his visit to the temple," he said.
Lalu Prasad visited the Sanjay Gandhi Zoological Park here last week to offer prayers at a temple inside the park premises with his security guards carrying sophisticated weapons. The visit had sparked controversy with the zoo authorities ordering a probe.
Kumar said formal inquiry report would be received in a week.
