Police are urging the driver of a black Audi who took an 11-year-old boy home following a collision in Huddersfield in May to come forward.

The collision happened at the junction of Manchester Road, Slaithwaite, and Hollins Row at approximately 5.30pm on Thursday, May 15.
The 11-year-old boy involved, who lives locally, suffered a broken and dislocated ankle.
