The immigration authorities at the Chennai airport were surprised to see Parvathi, mother of slain LTTE leader Prabakaran, when she landed from Malaysia with a valid medical visa at the airport here on Friday night.

The reason: her name was on the ‘Warning Circular' list of the Union government. Whenever a person's name finds a place in the list, the visa issuing authorities must obtain the approval of, or consult, officials of the Home Ministry before issuing him or her a visa. Though Ms. Parvathi's name was on the list, she got a medical visa.

Sources in the Immigration said both Velupillai and his wife Parvathi were living in Tiruchi till 2003. Soon after they migrated to Colombo, the Tamil Nadu government requested the Centre, in the same year, to ban their return. Accordingly, the Union government banned their entry into the State and put their names on the list.

Ms. Parvathi was sent back to Malaysia by the same flight.
