Street fights broke out between Nationalist Congress Party (NCP) and Maharashtra Navnirman Sena (MNS) workers in several areas of Maharashtra, including Thane and Mumbai, yesterday evening. Five people were injured.
Police said an inspector was also hurt in the incident. Meanwhile, Thackeray escaped unhurt.
Police had to resort to lathicharge to control the situation.
The incident took place at around 8.30 pm at Bhingar in the western Maharashtra district, about 125 km from Pune.
Around 50 NCP workers had gathered at Bhingar, where Raj was visiting for party-related work, to protest against his criticism of senior party leader and Deputy Chief Minister Ajit Pawar.
The MNS chief has been critical of NCP leaders at his recent public rallies. He has especially targeted Ajit Pawar, holding him responsible for the severe drought in the state.
