Baltimore police say they are making progress after identifying a recent pattern of robberies in the Canton area. 

In the past few days, there have been at least three robberies there, including a woman who had a gun placed to her head while unloading groceries at O'Donnell Square on Monday night. Around the same time, a man walking in the 300 block of S. Wolfe St. was robbed by two men of his wallet, including his military ID. 

And the day before, a man was robbed while walking in the 2100 block of Fleet St. around 10 p.m. and was robbed by two men, one who had a silver revolver. The victim was thrown to the ground and told to stay face down as they fled. 

Southeast District Maj. William Davis believes detectives are making inroads in the case, according to a spokesman. Street robberies in the Southeastern District, which includes Canton, Fells Point, Greektown, Highlandtown, and McElderry Park, are up 11 percent, police statistics show.

"We've identified a pattern of individuals that might be involved in several robberies," said police spokesman Anthony Guglielmi. "We have a good suspect description, and have reviewed surveillance video that's been helpful. They're in a very good position in terms of identifying who's responsible."

Elsewhere in the city:

A delivery driver was carjacked and assaulted in the 2100 block of W. Lexington St. at about 11 p.m. Wednesday. As he made a food order, one man jumped into his car and two others assaulted him, including striking him over the head with a glass bottle, police said. They took his vehicle and fled. Police tracked the vehicle to the 1500 block of W. Lexington St., where they said the suspects bailed out. A "person of interest" was located in the basement of a home in the block and is being questioned, Guglielmi said. 

A 40-year-old woman walking in the 800 block of N. Calvert St. at 6 p.m. Wednesday was robbed at gunpoint of her engagement ring, wedding band and sapphire ring. The man also asked for loose change, said he was sorry, and fled northbound on Hunter Street toward Eager.
