The Prevention of Terrorism Act of 1978 is a law in Sri Lanka. It provides the police with broad powers to search, arrest, and detain suspects. It was first enacted as a temporary law in 1979 under J. R. Jayewardene presidency, then made permanent in 1982.
Elements of the Act.
Under the PTA of Sri Lanka, a person can be detained for periods up to 18 months (renewable by order every three months) if the Minister has reason to believe or suspect that any person is connected with or concerned in any unlawful activity. Unlawful activity includes even pasting posters on walls, and is punishable with death.

For example, if a person knows the whereabouts of terrorist (“terrorist” not defined in the Act) and if such person fails to inform the police, he commits an offence punishable with a minimum 5-year jail term. If the terrorist stays with any person for a night such person is guilty of harbouring, punishable with a maximum of twenty years' jail.
