A 32-year-old man who allegedly sexually assaulted a one-and-a-half-year-old girl in his neighbourhood last week, was arrested on Thursday.

Kumaran alias Muthukumaran, a resident of a TNSCB tenement in Nochikuppam, allegedly sexually assaulted the child after which the girl’s mother lodged a complaint.

When Kumaran went into hiding, the Mylapore police questioned his mother Kasturi.

Unable to bear the embarrassment, the 58-year-old woman committed suicide by hanging last week.
