EAST NORWALK - Police are investigating a stabbing Sunday at a home in East Norwalk.

The stabbing happened at about 3 a.m. Authorities say the victim was taken to Norwalk Hospital and is in serious condition.

The incident happened at a rented house that neighbors say is occupied by too many tenants. Neighbors say the house, at 256 East Ave., is on a quiet street just a few blocks from the water.

Neighbors say there have been issues at the house besides the stabbing. In 2006, a fire broke out on the second floor. The house remained empty for a year. Then, six months ago, another large group of people moved in.
