Howard County Police are investigating whether two robberies and an attempted burglary occurring over a three-day span in the area of Swift Stream Place in Columbia are related, according to police spokeswoman Mary T. Phelan.
In all three incidents, police report the robberies were committed by three men.
The first incident occurred at 8:26 a.m. on Oct. 20 when officers received a call from a resident living in the 10300 block of Swift Stream Place, who said he saw three men turning door knobs along the hallway.
The resident heard his door knob turn, opened the door, and observed the three men, police said.
The three men then fled toward Little Patuxent Parkway, police said.
Less than 10 minutes later, police received a report of a robbery along the Route 29 footbridge.
Police said a woman was walking across the footbridge when she was approached by two men, who grabbed her purse.
Police said when the woman would not let go, the men reached into her pocket and stole her iPhone.
Police said the two men, along with a third, fled toward Stevens Forest Apartments.
The third incident occurred early Monday morning on a footpath located near the 10300 block of Swift Stream Place.
Police said a man was walking his dog between 12:30 and 1:30 a.m. when he was knocked to the ground by three men.
Police said the three men started kicking and punching the victim, and stole his wallet, cigarettes and lighter.
Police said the investigation of these incidents is ongoing.
