A father and his teenage son drowned in a canal after a Mercedes they were test driving 'flew off the road' and entered the water upside down, an inquest was told.

Grimsby Town youth team footballer Cameron Walsh, 16, and his father David, 40, had hired the car from a Mercedes dealership when it spun out of control in Tetney, near Grimsby, Lincs, on January 6 last year.

It hit a telegraph pole before flipping onto its roof and becoming submerged in the canal, Greater Lincolnshire Coroner's Court heard.

An inquest was told that Cameron had been messaging his friends about the car just minutes before it entered the canal running alongside Tetney Lock Road.

Emergency services were called at 1.38pm, but Cameron and his father were pronounced dead at 2.58pm. The cause of death for the pair was recorded as drowning.
