Repair crews filled in a sinkhole that opened between two houses in a sprawling Florida retirement community.

The Villages Daily Sun (http://bit.ly/QrD0tg ) reports the homes were vacant when the sinkhole, which was already under repair, expanded Saturday morning. Neighbors noticed the sinkhole was growing and alerted authorities.

Officials say crews from a Tampa firm had been working on the sinkhole for about three weeks.

District Public Safety Battalion Chief Pete Carpenter says the sinkhole opened up and expanded under the foundations of both houses. Officials blocked off traffic Saturday as crews returned to assess the situation.

Carpenter says the sinkhole was plugged by Saturday night.
