A THREE-YEAR-OLD girl has been killed following a collision in Royston launching a police appeal for witnesses and information.

The incident is believed to have taken place at around 3.06pm on Sunday near the White Bear pub, Kneesworth Street.

It is alleged a red two-seater Mazda sports car collided with two children.

The first child, a three-year-old girl, later died in Addenbrooke’s Hospital, Cambridge, the other, a five-year-old girl, was uninjured.

A man in his 60s has been arrested and questioned in relation to the fatal collision.

Inspector Matt Thompson said: “This is a tragic incident. We are very keen to hear from anyone who saw the road traffic collision and so may be able to explain how it happened.

“This is quite a busy road, with the White Bear pub nearby, and people may have seen the collision take place while they were out and about.

“They could have been outside the pub at one of the tables or inside looking out of the window and seen something.

“If anyone witnessed anything and did not speak to officers at the scene, I would ask that you contact me via the non-emergency number 0845 33 00 222.”

The police helicopter assisted in the investigation and roads were also closed.
