Lawrence police are investigating a break-in at another Lawrence business, the fourth business burglary this week.

Officers were called to Mass Street Music, 1347 Mass., about 11:30 p.m. Tuesday.

Police spokesman Sgt. Bill Cory said a witness heard a window breaking at the business and called police.

When officers arrived, the suspect was gone.

According to police reports, a cash drawer and $200 in U.S. currency was stolen from the business. The total estimated loss from damages and stolen property was more than $1,700.

Three businesses in west Lawrence were broken into about 1 a.m. Monday. Those cases remain under investigation.
