Business is back to normal at the Starbucks coffee shop and Noodles & Co. restaurant at the Arborland shopping center in Ann Arbor following bomb threats Saturday.

Police went to the restaurants with a bomb-sniffing dog from the University of Michigan Department of Public Safety about 4:30 p.m., Ann Arbor police Sgt. Mike Lance said.

The restaurants were checked and no bomb was found. People were allowed back into the restaurants, but about 5:20 p.m., the Noodles & Co. restaurant received another bomb threat, Lance said. Police returned to the restaurant to check it out, but nothing was found.

Police were still on the scene about 6:30 p.m. but the businesses had resumed normal operations, said Ann Arbor Police Sgt. Craig Flocken. Police were still investigating and had some leads in the case, Flocken said.

The restaurants are located at 3601 Washtenaw Ave.

In Michigan, a person convicted of making a bomb threat can be punished by up to 4 years in prison and/or a $2,000.00 fine.
