The JVP opposed the arrival of the IPKF and revolted against the pro-Western J. R. Jayawardene led government.

They named the UNP government as traitors and created the "Patriotic People's Movement" (DJV) which carried out the attack.

Assisted by a SLAF deserter, Mahinda, under the directions of Shantha Bandara and Gemunu (Premakumar Gunaratnam), the JVP seized 12 Type 56 assault rifles, seven sub-machine guns and ammunition.

The attack was carried out by a paramilitary of the JVP, Patriotic People's Armed Troops.

Kosala stated that these weren't against the Sri Lankan army but attempts made to collect weapons and arm themselves for the conflict.
