Deshmukh got into a row with Dr Sumit Ambade at the government rural hospital at Karanja yesterday, after complaining that a person, admitted for scorpion-bite, was not getting proper treatment.
He allegedly beat up the doctor severely and hurled casteist remarks against him. Ambade lodged police complaint against Deshmukh and nine others last night.
Inspector V M Chowdhury of Karanja police station said the police arrested Deshmukh and five other Sena activists today. Apart from assault, Deshmukh was also booked for offences under the SC/ST (Prevention of Atrocities) Act.
Sena is part of the BJP-led ruling coalition in the state.
