Milwaukee Jewish center forced to close after emailed threat

A Jewish community center in Milwaukee was forced to close on Tuesday after receiving an emailed threat overnight, it said on Facebook.
The Harry and Rose Samson Family Jewish Community Center is the latest target in a surge of violent threats against Jewish centers and schools in the United States in recent months. It was evacuated once last month and once in January after receiving phoned-in bomb threats, local media reported.
A federal investigation into phoned and emailed threats against Jewish groups across the nation has yielded one arrest. Disgraced former journalist Juan Thompson, 31, was charged in St. Louis on Friday with using fake email accounts to make bomb threats against Jewish groups while posing as his ex-girlfriend.
US authorities said they were examining more than 100 threats made against Jewish community centers by phone this year, which appear unrelated to the Thompson allegations.
