Karunaratne, 30, was taken into custody following the pre-dawn accident that resulted in the driver of a three-wheel taxi being taken to hospital.
“We have released him on personal bail, but he was asked to be in court on Monday for a magisterial inquiry,” a police spokesman said, adding that his vehicle was detained.
The incident comes as Sri Lankan cricket officials mull who to name as captain of the one-day squad for the World Cup hosted by England and Wales from May 30.
Karunaratne, who led Sri Lanka to a stunning Test series victory against South Africa last month, had been in the frame to lead the one-day side as well.
Sri Lanka’s cricket board said it would investigate the incident.
“Sri Lanka Cricket will also follow the due process as per his ‘Player Contractual Obligation’ … and conduct an inquiry in order to take necessary action,” the board said in a statement.
