Ten Nigerians are among 13 foreign nationals arrested by police for violating Sri Lankan immigration laws during their stay in the country, police said on Monday.
The others arrested for the crime include one Indian, an Iraqi and a Thai national staying in different parts of the Lankan capital, police spokesman S P Ruwan Gunasekara said.
They were produced in the courts today, he was quoted as saying by the SundayTimes.
The arrests have come after the Sri Lankan government beefed up security measures following the country's worst terror attacks on Easter Sunday, killing 253 people and injuring 500 others.
A total of 106 suspects, including a Tamil medium teacher and a school principal, have been arrested in connection with the Easter Sunday blasts.
