Kolkata, July 18 -- Five people including four school children were killed after a passenger train hit a pool-car and a bicycle at a manned level crossing in West Bengal's Murshidabad districts on Friday morning, officials said, adding that the gateman has been arrested. The incident took place around 6.40 am at a level crossing between Khagraghat Road and Karnasubarna railway stations near Berhampore. "The gateman incorrectly opened the level crossing to allow some vehicles through. But suddenly the Nimtita-Katwa train, which was also scheduled to cross that spot around the same time, came and hit the SUV," said a railway official. Police said that seven children were travelling in the SUV. While two children and a cyclist died on the spot, two more children succumbed to injuries at a hospital later, police said. Three other kids and the driver of the pool car were rushed to the hospital. One of the children was released after treatment while two kids and the driver are undergoing treatment. All the children were below 10 years old. While the gateman Anup Karmakar, 37, has been arrested, another official Kaushik Mal has been suspended. An investigation has been launched, police said....
