The NYPD is seeking the public’s help with a burglary pattern across Brooklyn and Queens that includes a $1,700 bicycle taken outside 812 Grand Street and cash and an iPad taken from businesses on Graham Avenue and Grand Street in East Williamsburg in September.

The NYPD Crime Stoppers notice, which offers a reward of up to $3,500, ties the three East Williamsburg thefts in the 90th Precinct to incidents in Queens’ 102nd and 110th precincts. The case was still listed as open on the Crime Stoppers site on Nov. 11.

The first theft came at about 5:28 p.m. on Wednesday, Sept. 16, when a 28-year-old woman left her bicycle, valued at $1,700, unattended in front of 812 Grand Street and someone took it, according to the notice. At about 9:35 a.m. on Sept. 29, someone entered a business at 80 Graham Avenue and took $300, and at about 8:40 p.m. the next day someone entered a business at 810 Grand Street and took $700 and an iPad worth $500, the notice says. The NYPD’s complaint records list the Graham Avenue theft, at a fast-food restaurant, as a commercial burglary and the Grand Street theft, at a restaurant, as a grand larceny.
