Breach of Peace by Politician

Kamlesh, a local MLA, while campaigning, creates a ruckus outside a school and disrupts the morning assembly. The Principal files a complaint under Section 188 of the IPC and Section 54 of the Bombay Police Act (BNPS) for obstruction and creating a disturbance in a public place. However, when the police try to arrest Kamlesh, his supporters attack the officers, and a minor clash breaks out. Now, the police want to book Kamlesh under Section 141 of the CrPC for causing breach of the peace.

What legal remedy is available to the police to hold Kamlesh accountable for his actions and the subsequent clash? Is this a case of 'breach of peace' under Section 141, and if so, what's the consequence?
