A 54-year-old Mumbai teacher who allegedly molested pupils at his school was arrested on Tuesday, according to media reports.

Police allege that Balchandra Bhangale, who was honored with the Best Teacher award a few years ago by the Mayor of the Ulhasnagar Municipal Corporation, took three boys and two girls to an empty classroom on a disciplinary pretext and molested them.

The school’s principal and trustee said there had not been any complaints against him in his 27 years on staff, but stressed that they would fully cooperate with the investigation.

Balchandra has denied the charges.
