Stray incidents of violence marred the 24-hour Assam bandh called by the All Assam Students' Union on Monday. The bandh brought life to a complete halt in the state.
Two motor-bikes were torched, while some private cars were seized by crowds in Jalukbari near the Guwahati University, sources said.

A large number of AASU activists surrounded the North East Frontier Railway headquarters at Maligaon and prevented employees and officers from going in.
The bandh has been called in protest against the recent assault on Assamese train passengers in Bihar and is being supported by several parties and organisations, including the Asom Gana Parishad, the Bharatiya Janata Party, the All
Bodo Students Union and the North East Students' Organisation.
A railway spokesman said all trains left Guwahati on Monday morning as per schedule, but he had no information on whether the trains were stopped anywhere by protestors.
"The exact information will be available at the controls, but the activists are preventing us from entering our offices and as such we do not have the information," he said.
Picketing and road blocks in different parts of the state by AASU activists prevented people from reaching their destinations.
All flights to and from Guwahati, however, operated as per schedule, airport sources said.
