Aurangabad: The Aurangabad police has cracked a seven-month-old murder case using just a tiny piece of evidence -- a shirt button from the crime scene. The police on Wednesday arrested Ajay Gulabrao Ragade (30), Chetan Ashok Gaikwad (34) and Sandip Asaram Gaikwad for robbing and killing wine shop employee Bhikan Niloba Jadhav (48) in Sillod city of Maharashtra's Aurangabad district, superintendent of police Mokshada Patil said.

The police only had a shirt button for evidence in the crime that took place on May 12 this year, she said. The police team couldn't recover any concrete from the scene of crime apart from a shirt button with the words 'rope last stitch' engraved on it, the senior officer said.
