At least 141 people including children, and women, were killed after a bridge collapsed in India's Gujarat state on Sunday and Police arrested nine persons in connection with the collapse.
Four of detained persons are employees of a firm contracted to maintain the bridge in the town of Morbi.
The 140-year-old suspension bridge - a major local tourist attraction - had been reopened only last week after being repaired.
The 230m (754ft) bridge on the Machchhu river was built in 1880, during British rule in India.
