Sri Lanka batsman Mendis arrested over fatal crash
The 25-year-old batsman was driving an SUV at Panadura before dawn when the incident happened, police said.
Mendis has been named in the 16-player squad for a two-match home Test series against England in March, but the tour was cancelled because of the coronavirus pandemic.
More than 3,000 people are killed annually in traffic accidents in Sri Lanka.
A former spin bowler, Kaushal Lokuarachchi, was given a four-year suspended jail sentence for crashing into a woman pedestrian and killing her in 2003.
