Two men were injured during violent muggings in Manhattan yesterday afternoon. The first happened outside a Soho clothing store, while the second was on an Upper West Side street.

A large group was waiting outside the Supreme store on Lafayette Street for the company's new spring/summer collection, when the attack occurred around 2 p.m. PIX 11 reports that the victim was leaving the store when a man walked up to him and demanded his shopping bags. Police tell the station that when the victim refused, the man "cut him across the face with a sharp object before fleeing."

A witness said, "Some guy came up to him, and said gimme the bag. And he said no. And with no reaction, he just sliced him up."

A teen told the Post, "His right cheek was bleeding. It was all leaking." The victim was taken to the hospital while the suspect, who was apparently wearing a ski mask, fled.

At 4:55 p.m., police say that a 33-year-old man was approached by a male suspect in front of 105 West 88th Street: The suspect "grabbed the victim from behind, placed a knife to his neck and demanded his property." The victim handed over his Kindle and Apple headphones, but then a struggle ensued. Police say the mugger stabbed the victim in the upper back before fleeing eastbound on West 88th Street.

The victim was taken to St. Luke's Hospital and is in stable condition. The suspect—who is described as being in his mid 20s, 5'9" and 160 pounds with a thin build and was least seen wearing a blue jogging jacket, blue jeans, black Nike sweatshirt, black sneakers and a red baseball cap—was captured on video:

The violent muggings come less than 24 hours after a waiter was slashed by a teen apparently soliciting donations at the Silver Spurs diner near NYU on Wednesday. A forensic psychologist, Dr. Jemour Maddux, told PIX 11 that "what’s happening on the streets may be a combination of a raw increase in criminal activity and the theory posed by NYPD Commissioner Bratton—a slashing spree fueled by the media’s fixation on the incidents."

Dr. Maddux explained, "This is a public health issue, this connecting these different things. And that’s what all of these individuals have in common. They have the media in common. And it’s my opinion they have psychiatric issues in common. When you see that they have operated in some of the same systems, you wonder if there’s a public health view of this situation can capture the variability that we’re seeing cross these different perpetrators."
