Udhagamandalam: The Nilgiris has tightened security at all the 16 check posts in the district, where e-pass has been made mandatory for entry.
A team comprising police, health and revenue officials are deputed at all the check posts.
Police said the vehicles without e-pass were being sent back.
“The number of vehicles entering the district has drastically come down since the introduction of e-registration system,” said a police source.
At least 10,000 vehicles used to enter the district in a week during the past month.
At least 60% of them was private vehicles, said Nilgiris collector J Innocent Divya.
“As the e-pass system has come into force, we are scrutinizing all the applications.
Passes will be granted only for emergency cases and on medical grounds,” she said.
