Montgomery was arrested Monday on suspicion of robbery, attempted robbery and felony vehicular evasion.
According to a Police Department news release, Montgomery is a suspect in five robberies or attempted robberies. One took place June 23 and the other four occurred Monday.
On June 23, Montgomery allegedly entered a Subway sandwich shop in the 1500 block of West El Camino Avenue at 7:55 p.m., pointed a gun at a female employee and demanded money. The employee called to a co-worker in the back of the store and the suspect fled.
At 2:09 p.m. Monday, officers were dispatched to a robbery that occurred at gunpoint at Little Caesar's restaurant in the 2400 block of Rio Linda Boulevard. They were told that a suspect entered the business, produced a handgun, then left on foot. Nothing was taken.
A few minutes later, at 2:22 p.m., police received a report of a robbery at a Subway shop in the 4200 block of Norwood Avenue. In this case, the suspect entered the business, produced a handgun and fled with cash.
At 2:59 p.m., officers responded to a report of a robbery by an armed man at another Subway shop, in the 2500 block of West El Camino Avenue.
Montgomery was taken into custody following a fourth robbery Monday. This one was reported at 3:20 p.m. at CPC Bakery in the 1200 block of El Camino Avenue. Officers arrived just as the suspect vehicle was leaving the area.
A lengthy vehicle pursuit ensued. When the vehicle finally stopped, Montgomery allegedly got out, and challenged and confronted the officers, who used a "conducted energy device" to detain and control him, police said.
Montgomery is being held in Sacramento County Jail in lieu of $300,000 bail.
