Several BJP workers were detained by the police on Wednesday for their plan to throw empty vessels towards the convoy of Maharashtra Chief Minister Uddhav Thackeray before he addressed a rally here, a senior official said.

BJP's Aurangabad city unit president Sanjay Kenekar, Raju Shinde and other women workers of the party had earlier told that they would hand over a memorandum to Thackeray to highlight the water woes in the city. But later they came to a hotel, where the chief minister was to stay, he said.
