The Forest department captured a tigress last night after it strayed into a village at Hingalganj, adjacent to the Sunderbans in North 24-Parganas district.
It was released today into the Baghmara forest deep into the Sunderbans, the officials said.
On Thursday, a tiger had entered Shamsernagar village after swimming across the two-km wide Raimangal river. It killed livestock before being trapped by the Forest department staff the next day.
It was released into the deep forests on Saturday, they said.
Forest officials said tigers had been regularly entering human habitations ever since cyclone Aila wrought havoc in the Sunderbans.
One of the reasons for frequent cases of tiger straying is the dwindling prey base in the Sunderbans, possibly caused by cyclone Aila, they said.
