Three accidents on Friday and Saturday, two near the capital and one in Lohardaga, led to as many as six deaths.

A teacher and his son died in a road accident at Jamatola, some 70km from the capital in Silli on Saturday morning.

Jayant Banerjee, 40, an English teacher at RTC School, Silli, was riding his bike with son Jeet, 15, a class IX student sitting pillion, when a speeding truck with cement hit the two-wheeler from the back.

The father and son died, but the truck driver managed to flee. Residents blocked the road for an hour after the mishap. Rural SP Rishav Kumar Jha said they filed a reckless-driving FIR against the man.

On Friday night, four persons — a man, two women a child — died and nine sustained injuries when a truck ran over two autorickshaws at Kujra village, Lohardaga. One autorickshaw had passengers returning home from a burial and another had students coming back after appearing in their Intermediate exam.

Bystanders set the truck on fire. Lohardaga SP Priyadarshi Alok said the nine injured were sent to RIMS, Ranchi, of whom one was critical.
