Yogesh Khandeparkar, who was missing from his house since the girl lodged a police complaint against him yesterday, was arrested today, police said.
In her police complaint, the girl mentioned that the teacher molested her twice in the school, last month.
Initially, the victim could not muster courage to file a police complaint but did it after an NGO came to her support.
Meanwhile, Ponda police inspector Jivba Dalvi, investigating the case, said the accused was admitted to hospital, as he complained of ill health during his medical check up, after the arrest.
