Calcutta, Jan. 14 :     Five persons were killed and four seriously injured when a speeding Tata Sumo hit a stationary lorry from behind on Vidyasagar Setu around 8 am today. The Sumo was coming towards Calcutta from Sibpur when the accident occurred. Two of the victims were women. The driver, who had a miraculous escape, is absconding. Joint police commissioner (traffic) V.V. Thambi said the cause of the accident was reckless driving and not fog, as was being claimed by some people. 'At the time of the accident there was no fog,' the police official said. 'The Sumo was coming at breakneck speed and the driver, probably absent-minded, did not see the lorry parked on the bridge.' The lorry was stuck there following a breakdown. The victims were identified as Sandip Sinha (25), Sadhan Das (27), Sadhana Bagchi (35), Soumit Roy (19) and Rita Bag (17). They were probably office-goers, preliminary investigations revealed. The Sumo, used for commercial car pool, ferried office-goers from Howrah to Calcutta. The four injured were admitted to SSKM hospital in a critical condition. The victims were residents of Chatterjee Para and Bangal Para in Shibpur. Officers who visited the site said three of the victims died on the spot, while two succumbed to their injuries at the hospital. 'We are trying to get more details about the accident from the injured. But they cannot speak yet,' an officer said. The excuse of poor visibility due to dense fog has been used by several errant drivers in the past few days. There have been at least four accidents in as many days during early morning. However, the weather office today confirmed that visibility even in early morning fog is at least two kilometres. The police have told drivers to use fog lights and not to exceed a speed of 25 kmph.
