A stray dog, named Coke by residents of Gangotri building at Jangid Complex in Mira Road near Mumbai, was beaten up allegedly by miscreants who had come to smoke marijuana on the premises on Tuesday night. Coke sustained multiple spinal fractures and is battling for its life at the Society for the Prevention of Cruelty to Animals (SPCA) hospital in Thane. The dog was sleeping on the road outside the building around 11.40 pm when seven boys walked up to him and started hitting him with bamboo sticks. The security guards protested but the boys threatened them, said Shakuntala Majumdar, a resident. By the time the building chairman arrived, the boys fled on their two-wheelers. Coke was taken to the SPCA hospital on Ghodbunder Road and Majumdar filed a complaint with the Kashimira police. Doctors said it would take at least 72 hours to determine whether the dog would survive. The strayhas also lost vision in its left eye. According to the residents, the boys attacked the dog as it would bark at them every time they came to the compound to smoke grass. Cops, say residents, have picked up trouble-makers, but the menace continues.
