A string of crimes have hit the Elm City, including one robbery of a store just across the street from Old Campus.

In the past week, there have been 11 robberies in the city, covering almost every neighborhood in New Haven. Along with armed thefts in the Hill, Fair Haven and Beaver Hills, a clerk at College Convenience and Deli near the corner of Chapel and College Streets was threatened and robbed.

At approximately 9 p.m. on Sunday, an unidentified black male reportedly in his 20’s jumped the counter and pushed down the clerk at College Convenience, located just south of campus, New Haven Police Department spokesman Joe Avery said in a press release.

The College Convenience clerk on duty that night, who would not give his name, said the intruder never actually displayed a gun.

“[The robber] has something in his sweater and he kept moving it around and threatening to take it out,” he said. “I could not tell for sure if it was a gun, but it looked like it.”

Given its proximity to campus, many members of the Yale community visit College Convenience, but one student said she is not affected by news of the potentially armed robbery.

“I would probably still go into College Convenience if I were in the vicinity,” said Claire Wallace ’12, who said she frequents the store.

Ten other robberies, three reported shootings and a narcotics bust also hit the Elm City since last Saturday, spanning the extent of the metropolitan area. To the east of the Yale campus, Fair Haven and Fair Haven Heights saw four robberies.

Three of those robberies along with two assaults with a motor vehicle were perpetrated on Sunday between 7:57 and 9:15 a.m. These crimes are believed to have been orchestrated and committed by a group of four juveniles in a stolen 1990 Dodge Caravan, Avery said.

The juveniles were arrested on multiple charges including intentionally striking individuals at 96 Front St. and 416 Forbes Ave. with their vehicle.

In addition to Fair Haven, the area to the South of Yale’s campus known as the Hill was also hit by crime in the past week. The Hill, which is home to Yale-New Haven Hospital, saw two robberies and one shooting within a four block area .

Although crime levels decreased last year, police and city officials have admitted that budgetary problems may hinder further progress against crime. New Haven has a projected $52 million budget deficit for this year, Mayor John DeStefano Jr. said earlier this month.

“[This coming year] is going to be a resource-poor environment for us,” he said, adding that the deficit will force the city to cut some police services and to halt the recruitment of any new officers.

There were 570 robberies in New Haven in 2010. This represented a 13 percent decrease from 2009.
