The suspects gained entry by forcing open a ground level window, police said.

Then, at approximately 1:25 a.m., while detectives were processing the McKnight Court residence, patrols received a call for a residential burglar alarm on Stockton Drive.

 Upon arrival officers confirmed an attempted entry to the residence.

According to police, the suspects were apparently startled by the alarm and fled the area.

This is now the third incident of this type in the Cranbury Greene development within the week, police said.

“We are very concerned with these incidents and we are using all our resources and working with other law enforcement agencies in an attempt to bring these incidents to their natural conclusion through arrests," Cranbury Police Chief Rickey Varga said. "Nighttime residential entries such as these are of serious concern. The likelihood of having a homeowner/suspect confrontation is greatly escalated during these hours, such a confrontation could bear tragic consequences."

In the McKnight Court incident the homeowners were not at the residence at the time of the burglary, police said.

However, the homeowners were home and asleep during the Stockton Drive attempt.

Police are urging residents to be extremely vigilant, and to report any suspicious persons, vehicles or suspicious activity.

If residents have an alarm system, they should arm it, not only when they are away, but when in for the night, police said.

Residents should also check to make certain all windows and doors are locked and ensure exterior lighting and motion sensor lights/bulbs are operational daily if possible.

If something is found amiss or appears to have been tampered with, notify police immediately, police said.

The Cranbury Police Department would like to remind residents that it provides free residential home security surveys/assessments.
