New Delhi, Nov 24 After three deaths in two days in accidents on the newly-constructed Signature Bridge, Delhi Chief Minister Arvind Kejriwal on Saturday appealed to the youth to "be careful while clicking selfies and not drive at a high speed"."I am extremely concerned about the accidents on Signature Bridge. It is Delhi's pride. It is my appeal to all the people, especially the youth to be careful while clicking selfies on the Signature Bridge and not drive vehicles at a high speed. Your life is precious to the country and for your parents," Kejriwal tweeted.On Friday, two medical students on a motorcycle were killed after they rammed into a divider on the bridge and fell into the Yamuna river.Friday's accident was followed by another accident on Saturday morning which killed a man after his bike skidded and he hit the divider head-on.Aam Aadmi Party's (AAP) chief spokesperson Saurabh Bharadwaj, on the other hand, blamed the Delhi Police for its inaction in a series of tweets."What is the Delhi traffic police doing? Why were no traffic police personnel deployed to check over speeding at the Signature bridge? Is Signature bridge not under their exclusive jurisdiction?" Bharadwaj asked.He said that since the Delhi government does not have its own police, the Central government and Lt. Governor Anil Baijal were "duty bound to ensure law and order at each corner of Delhi including the Signature Bridge"."News is published every day about dangerous stunts while taking a selfie. Is it not the duty of the Delhi Police to control such things? Has the Lt. Governor suspended DCP Traffic for failing to deploy traffic police at the Signature bridge?" the AAP MLA from the Greater Kailash constituency said.
