More than 15,000 Mumbai police personnel will be on duty at venues of Dussehra rallies of rival Shiv Sena groups, for an ICC cricket World Cup match on Tuesday and for overseeing immersion of Goddess Durga idols after the end of Navratri festival, an official said on Monday.

The ruling Shiv Sena and its rival group led by former Maharashtra chief minister Uddhav Thackeray are holding their Dussehra rallies at Azad Maidan (south Mumbai) and Shivaji Park in Central Mumbai's Dadar, respectively, where police personnel will be deployed in strength.
