Personal life
Shanmugalingam Sivashankar is an "introvert," who is rarely seen in public and is known to the public by his nom de guerre rather than by his real name. He has a wife and three children, their whereabouts is unknown. He is a hardliner in favour of an independent Tamil Eelam.

LTTE
Pottu Amman joined LTTE in 1981 along with Colonel Soosai, and became second in LTTE's military wing after leader Velupillai Prabhakaran. Pottu Amman was trained and was the head of  a coastal camp in Vedaranyam in Tamil Nadu. He also became the leader of the Black Tigers force and Tiger Organization Security Intelligence Service (TOSIS). He was once kidnapped by rival PLOTE cadres and later freed in 1985 in exchange for another PLOTE member. Pottu Amman is known for his military expertise.

Black Tigers
Pottu Amman is responsible for training Black Tigers for missions which cost them their lives. Most notably was when former Indian Prime Minister Rajiv Gandhi was killed by a women tiger who was allegedly raped by the IPKF. Another attack was against president Ranasinghe Premadasa who was killed when a Black Tiger blew himself up also killing 23 bystanders on May Day. He is also believed to have been in charge of planning the LTTE's covert operations and was the brain behind most of the LTTE's successful military operations.

TOSIS
Tiger Organization Security Intelligence Service was also run by Pottu Amman. He would send out cadres to check up in places like Colombo and see what the Sri Lankan Government were planning against the Tigers. He was responsible for getting many documents for many such attacks from the Sri Lankan Army. Once it took Pottu Amman and other officers one year to attack a base as they had to research what weapons the Sri Lankan Army had, what their military strength was and how many soldiers were there.

Rumoured Death
Sources closes to LTTE overseas operation recently mentioned that Pottu Amman was safely escaped with his loyalties and currently living in an African country. For his safety the details of how he escaped and where he resides are kept secret. There had been rumors that a rocket hit the ambulance he was riding, along with Velupillai Prabhakaran after a two-hour firefight in Vellamullivaikkal, 18 May 2009. What was claimed to be the Tamil Tiger chief Velupillai Prabhakaran's body was found in a mangrove island of Nanthikadal lagoon on the following day. Although all other Tiger leaders' bodies were identified, Sri Lanka Army was unable to identify the body of Pottu Amman among ten thousands of bodies decomposed beyond identification. Sri Lanka Army Commander General Sarath Fonseka later claimed that "he [Pottu Amman] is well and truly dead" as there had been no way out for him due to tight security around the area the last battle of Vellamullivaikkal fought. The Sri Lanka Defence Secretary Gotabhaya Rajapaksa is also quoted as claiming in desperation with more questions arising on Pottu Amman saying that he is "100% sure" that Pottu Amman is dead.

Initially this was believed to be true as there was no independent verification from within the warzone or from anyone other than Government officials but as months have passed from the supposed death of the LTTE deputy. The Sri Lankan government's reluctance to give a plausible account of the supposed demise of Pottu Amman and Interpol's decision to put him back onto the wanted list suggests Pottu Amman is still very much alive.
