In view of the rising use of 'koyta' or billhook by anti-social elements to terrorise and attack people in Maharashtra's Pune of late, the police have instructed the sellers of agricultural implements in the city to maintain a record of those buying such tools by noting down their Aadhaar card details, an official said on Thursday.

The move comes in the wake of a spurt in incidents of miscreants, including minors, attacking and terrorising people with koytas. Several incidents involving members of the so-called 'Koyta gangs' bullying people by brandishing billhooks, especially in areas located on the outskirts of Pune city, were reported in the past few months.
