According to Crime Branch of Thane Police, which claims to have cracked the case, the disposed body of Asif Shamim Shaikh (17), who lived in Mumbra near here, was found wrapped in a white gunny bag on June 2.
Thane City Police DCP Crime Parag Manere said the accused-- Puskan Havva Shaikh, 35 and Mohammad Habib Mohammad Khalil Shaikh, 25 --were traced to Mumbra and arrested yesterday.
Police suspect that the victim was killed and dumped in the luggage bogie of a Kalyan-bound local train from Mumbra to destroy evidence. Then the body was again transported to another local proceeding to Ambernath, from where it was recovered last week.
However, the motive behind the killing is not known and police were still interrogating the foursome.
