Three persons, including a child, were injured when a powerful bomb exploded at a sports stadium complex in Imphal West district of Manipur on Saturday.

The bomb was fitted in a car at Khuman Lampak stadium complex near here and went off at around 9.45 a.m. injuring three persons including a 10-year-old child, officials said.

The car was completely damaged in the explosion while the injured were passers-by, who were taking a stroll in the stadium complex, they said.

The explosion took place near the office of the Autonomous District Council (ADC), a hill-based panchayat like office.

Some hill-based organisations had opposed the election to the members of the ADC some months ago, saying hill areas should be placed under the provisions of the Sixth Schedule of the Constitution. This was opposed by the State government, saying the ADC gave enough powers to its members.
