Police in South Wales have launched a witness appeal after a cyclist died in Penarth.

Martin Trinder, aged 25 and from Cardiff, died of injuries sustained when he came off his bike on the descent of St Augustine’s Crescent at around 5.40pm on Wednesday 16 July.

It is believed that he may have lost control of his bike.

He was taken to University Hospital Wales in Cardiff, but died there last Tuesday 22 July, reports the Penarth Times.

South Wales Police have asked anyone with information to contact them on 101 quoting reference number 1400256228.

Born in Scotland, Simon moved to London aged seven and now lives in the Oxfordshire Cotswolds with his miniature schnauzer, Elodie. He fell in love with cycling one Saturday morning in 1994 while living in Italy when Milan-San Remo went past his front door. A daily cycle commuter in London back before riding to work started to boom, he's been news editor at road.cc since 2009. Handily for work, he speaks French and Italian. He doesn't get to ride his Colnago as often as he'd like, and freely admits he's much more adept at cooking than fettling with bikes.
