An armed robbery was reported at Eden Mill Park Wednesday afternoon, the third in a rash of violent gun-related crimes in Harford County this week.

In addition to the park robbery, a man was shot in a home near Aberdeen by gunmen when he opened the door Thursday morning. Another man was killed in Street early Monday by three suspects who broke into his home.

A 32-year-old man from Shrewsbury, Pa., reported the armed robbery at Eden Mill Park in Pylesville at 4:45 p.m. Wednesday, according to the Harford County Sheriff's Office.

The victim told police he was leaving the park with some friends when two men wearing masks accosted him, displayed a handgun and ordered him to empty his pockets, according to the press release.

The victim handed over cigarettes and his wallet, which contained money and personal items.

No one was injured in the incident. The suspects are described only as black males in their 20s, wearing nondescript clothes, one of whom was armed with a handgun and was last seen fleeing the area in a dark-colored car.

Sheriff's Office spokesman Lt. Michael Crabbs said it is unknown if the suspects and victim may have known each other. He noted the victim's friends did have consistent stories.

Aimee Dunn, of Eden Mill Nature Center, which is within the park, said she had not heard about the incident and could not comment on it as a county employee. She directed inquiries to the Harford County spokeswoman Sherrie Johnson.

"It's unfortunate, but we feel the park is safe and we hope the authorities can find the person who's responsible," Johnson said.

Early Thursday morning, a man was shot by two men when he opened the front door to an apartment in the Perrywood Garden community, in the 300 block of Mayberry Drive, just south of Aberdeen, according to the Sheriff's Office.

Raymond Green, 22, said he heard a knock at the door about 1:30 a.m., according to a news release. When he opened the door, he saw two men dressed in dark clothing standing on the stairs. One produced a handgun and fired it at Green, striking him in the upper torso, according to the release.

Green immediately closed the door and called 911. He was conscious and alert, treated at Harford Memorial Hospital in Havre de Grace and released, according to the release.

Green was visiting his girlfriend at the home, Crabbs said.

No motive has been determined, and Crabbs said he did not know if the victim and suspects had any connection.

Crabbs said the circumstances do, however, sound strange or suspicious.

"Originally [Green] wasn't being too cooperative but then he was more cooperative," Crabbs explained.

The suspects in the Aberdeen robbery are not believed to be connected with the fatal home invasion robbery in Street, Crabbs said.

Detectives are continuing to investigate both incidents.

Anyone with information on the Aberdeen shooting should contact the Sheriff's Office Southern Precinct at 410-612-1717. Information on the Eden Mill Park robbery should be directed to the Northern Precinct at 410-692-7880.

Despite two fatal shootings in Harford since late June and the latest armed robbery incidents, reported major crimes in general were down significantly in the first half of this year compared to the first six months of 2013, Harford Sheriff Jesse Bane said in early July.

The Sheriff's Office, which handles the bulk of the law enforcement duties for much of the county, said crime reporting data from the first six months of 2014 showed a 12 percent decrease in Part 1 Crimes, such as murder/manslaughter, rape, robbery, aggravated assault, burglary, larceny/theft, motor vehicle theft and arson. Only arson crimes had shown a slight increase.
