India, Sept. 5 -- The Mumbai Police will deploy more than 21,000 personnel to maintain law and order during idol immersions on Anant Chaturdashi, the tenth and final day of the Ganesh festival, on Saturday (September 6) in the city.

The police, meanwhile, said on Friday that they were on high alert after a threat call to the Mumbai traffic police helpline claimed that 34 "human bombs" with 400 kg of RDX had been planted in as many vehicles to trigger blasts "that would shake the entire city".

The police also said the Crime Branch has launched an investigation into the threat, and the Anti-Terrorism Squad (ATS) and other agencies have also been informed. They said the sender mentioned the name of an organisation called 'Lashkar-e-Jihadi'...
