The police said the accident occurred around 6.30 a.m. when the vehicles were moving on NH-24. A truck going towards Lucknow suddenly applied bakes, which led to the chain collision. Six cars were damaged badly and had to be removed by cranes. About a dozen commuters sustained minor injuries in the collisions.

"The driver of the truck said that he was forced to apply the brakes when a wild animal suddenly came on the highway," said the superintendent of police Panchsheel Nagar.
