MADISON, Wis. (WMTV) - Madison Police are investigating at least 14 violent robberies occurring in less than a month.
Madison Police Chief Mike Koval's blog said the city has seen a "rash of increasingly dangerous crimes, creating far too many victims!"
The blog said the crimes are carjackings, robberies and home invasions.
"To have so many violent robberies in such a short period of time is unusual for Madison," said Joel DeSpain, the public information officers for MPD.
Over the weekend at least three cab drivers were robbed. Green Cab was the victim to two of the robberies. The businesses pulled its drivers off the streets Saturday night, and on Monday began limited daytime service.
DeSpain said the department's violent crime unit is investigating this crime wave looking to see if there is a connection.
Koval's blog highlights a pattern "involving a group of young African American males who are armed and masked when they approach drivers, pedestrians and/or gas station employees (*no suspects been identified nor are there persons of interest at this time)."
A Union Cab drive was also the victim of a robbery. The president of the cooperative Jason Glomp said this is a reminder for drivers to be vigilant, and that safety is always a top priority.
"It's incredibly scary to have something like that happen. As a driver it's something that sticks with you for a long time," Glomp said.
Monday evening Madison Mayor Paul Soglin said the city will not enforce the 24-hour service ordinance for cab companies until the people behind these crimes are arrested.
The criminals aren't just targeting cabs. On Saturday, two men were robbed and beaten in their home. Madison Police are also looking into attacks that happened in drug store and daycare parking lots.
"We're seeing people with guns paces to their heads, being thrown to the ground, being pistol whipped," DeSpain said.
MPD is actively investigating the cases, but DeSpain said the cases are new and it could take time to find the two make suspects mentioned in Koval's blog.
