Another spur was also the impatience of Tamil youth in Sri Lanka. Veteran politicians noted that current youths were more ready to engage in violence, and some of them even had ties to certain rebel groups in South India. Also in 1974, there was conference of Tamil studies organized in Jaffna. The conference turned violent. This resulted in the deaths of seven people. Consequently, about 40 – 50 Tamil youths in between the years of 1972 and 1975 were detained without being properly charged, further increasing tension.
