GLENDALE, AZ - Authorities believe a Wednesday morning stabbing of a man is connected to three other armed robberies in the Valley.
Glendale police Officer Tracey Breeden said police received a 911 call just after 10 a.m. about a stabbing near 63rd Avenue and Mountain View Road.
Authorities said a 21-year-old male was transported to a local hospital with serious injuries, according to Sgt. Trent Crump with the Phoenix Police Department.
Crump said Phoenix police responded to three armed robberies Wednesday after the reported one in Glendale. Authorities believe that the robberies are related.
Officers responded to reports of an armed robbery near Camelback Road and 7th Avenue around 10:30 a.m. Police said a man was walking down the street and robbed of his belongings at knife point.
Authorities then responded to another armed robbery near McDowell Road and 37th Avenue where two juveniles were robbed at knife point. One of the victims was stabbed during the incident, but those injuries were not life threatening.
Crump said police responded to a fourth incident near 35th Avenue and Bethany Home Road where an adult male was robbed at knife point after exiting a city bus.
Authorities said the vehicle described in each of the incidents is a silver PT Cruiser. Crump said that police do not have any additional information.
Police said they are looking for three or four suspects, but do not have any specific information. A release said one of the victims was older, potentially between the ages of 30-40. The additional suspects may be teenagers.
