BU Students Robbed At Gunpoint Say They Were Cornered

BOSTON (CBS) - There's now a fourth report of an armed robbery at Boston University in the last two weeks.

According to an alert sent to BU students, two young black males between the ages of 16 and 20, wearing hooded sweatshirts and carrying a handgun, attacked the female victim at about 8:40 p.m. Tuesday at 808 Commonwealth Ave.

Boston University Police say the woman was not harmed and nothing was stolen.

On Wednesday, Boston University said they are now offering a $10,000 reward for information leading to the arrest and conviction of one of more of the perpetrators.

In the three other robberies, three suspects were reported, all wearing hooded sweatshirts.

Police released surveillance video showing one suspect with a red sweatshirt wearing Air Jordan sneakers. They believe he's connected to two of the robberies. Another suspect is wearing a grey sweatshirt with two numbers on it. One of the numbers is a six, but it's difficult to make out the second number.

Police could only trace one stolen cell phone for a brief period of time to Dudley Street in Roxbury, but the phone was then turned off.

The suspects are believed to be armed and dangerous.

On September 23, two BU students were robbed of money and smartphones by thieves with an automatic weapon.

Then, two nights later, three more people were held up at gunpoint a few streets away.

Two Boston University juniors tell WBZ-TV they were robbed by the fearless thieves as they walked from class in broad daylight on September 25. The students say they felt cornered by the three teenagers as one walked in front of them and two walked behind.

The one in front suddenly turned and pointed a handgun. "He pulled it out and said 'give me all your stuff' and I heard a click," said one of the victims. "I said do whatever they say." He was forced to hand over his laptop, wallet and cellphone, while a second victim had his pockets searched. "There was no money in my wallet and they only searched the front pockets, so they never found my cellphone."

The students say it happened so quickly and they were stunned at the time of day. They also thought that walking in a group they would be fine. "You definitely have to be aware of your surroundings," said one victim.

A third robbery was reported on Oct. 5 in which a man's iPhone, wallet, and keys were stolen near Thatcher and St. Paul Streets.
