The woman was attacked with acid at Chithera village here a few days back, the police said today, adding that the victim had suffered 10-12% burn injuries in the incident.
She was taken to a hospital for treatment and subsequently discharged.
Sources said the woman was recently involved in a scuffle with Sandeep (22), a police constable and a resident of the village.
The woman's dog had urinated on the wall of the police constable's house which had led to a scuffle between the two, they said, adding that the neighbours had to intervene to pacify Sandeep.
