Noida, Nov 18 (IANS): One of the 16 students who was injured after their school bus hit a pillar at the busy Rajnigandha Chowk underpass in Noida on Saturday morning, continues to be under observation at a private hospital, officials said.

The bus driver is also being treated for injuries.

The police said bus driver Gagan Saran lost control of the vehicle while it was heading towards the school around 8 a.m.

They said that 15 of 16 injured students were treated for minor injuries and allowed to go home.

Roshini, a student of class 11, sustained head injuries and was admitted to Kailash hospital.

A hospital official said in the evening that the girl is under observation and out of danger.
