The police arrested five persons for taking drugs near a newly-dug tunnel near Fort William, headquaters of the Eastern Command, here.
Some cables were also recovered from the tunnel measuring 3 to 5 feet which was discovered last night near a statue of Shyamaprasad Mukherjee, a senior police official today said.
"We have informed CESC, BSNL and other agencies to look into whether these cables belonged to them. We have launched an investigation into the matter," the official said.
A spokesperson for the Eastern Command said that the police was looking into the matter.
