Two days after a 3-year-old girl was found dead near here, police cracked the case with the arrest of her mother Wednesday, on charges of poisoning the child in a conspiracy hatched with her paramour, police said.
The body of the girl was found lying in a bush in Karatumedu in Saravanampatti limits in the city two days ago following which the 30-year-old woman had lodged a missing complaint.
Investigations revealed that the child was seen as an obstacle by her mother for continuing her illicit affair.
The accused woman gave poison-laced biscuits to the child and after confirming she was dead, her paramour took the body and disposed it of, they said.
The woman's paramour was absconding and a search is on, they added.
