Police have issued a further appeal for witnesses after a motorcyclist died from the injuries he sustained in a collision on the M23 on Wednesday, October 20.
Chi Hung Wong, 31, from Brighton, sustained serious injuries following the incident involving a Citroen C4, which occurred on the southbound carriageway near Pease Pottage about 9.10pm.
He has since died of his injuries.
A 55-year-old man from Worthing, who was driving the Citroen, was arrested on suspicion of drug-driving and later released under investigation.
A section of the road was closed in both directions due to the adverse weather conditions at the time.
Police are asking anyone who might have dash cam footage – in particular any lorry drivers – to email collision.appeal@sussex.pnn.police.uk quoting Op Maywood.
