One alleged purse-snatcher was arrested because a quick acting sandwich delivery man chased her down on his bicycle in downtown Grand Rapids.

Keean Mansour works for Jimmy John's and tells WOOD TV he saw the crime and went after the thief. He captured the alleged thief with the help of other passersby. He said he did not even think about it.

It was about getting the purse returned, he said. He also says he hopes that the suspect can get by without stealing purses in the future.
