According to the police media unit the Somali nationals had been adrift at sea for several days and were rescued by a Sri Lankan fishing boat.
The captain of the Sri Lankan fishing boat has said that he had set sail a month ago to catch fish and while out at sea he had seen the Somali boat.
He said that the four Somali nationals were taken aboard his boat and brought to the Modara fishing harbor today.
The Somali nationals were handed over to the Modara police and later to the harbor police for further investigations.
The navy is already on alert for Somali pirates who may enter Sri Lankan waters to kidnap Sri Lankan fishermen for ransom.
Recently six Sri Lankan fishermen were rescued by the Spanish Navy from the custody of Somali pirates after they were kidnapped last year.
The pirates had demanded a sum of US $6 million as a ransom for the fishermen. They had vowed to kill the fishermen unless they receive the money.
In January last year Somali pirates killed two Sri Lankan fishermen and took another three as hostages after their vessel got lost in the Indian Ocean. (Colombo Gazette)
