Police investigating the stabbing of Rabbi Zalman Gurevitch, co-director of Chabad-Lubavitch of Frankfurt, arrested a German man of Afghan descent, the Associated Press reported over the weekend.

The 22-year-old Frankfurt resident was arrested Thursday night following tips from users of an online bulletin board. The suspect apparently described in detail the events surrounding the Sept. 7 attack on Gurevitch, who was walking home from synagogue services when an Arab-looking youth allegedly stabbed him, shouting, "I'm going to kill you."

Many high-profile German politicians and Jewish community leaders visited Gurevitch in the hospital last week. He remained there over Rosh Hashanah and was expected to be released this week.
