Three teenagers charged in connection with two of four recent armed robberies near Boston University’s campus are all students at a charter high school in Boston, according to court documents.
Authorities said they continue to investigate whether those teenagers might have ties to the other two robberies. University officials urged students to remain vigilant.
Taquari Milton, 17, of Roxbury, an 11th grader at the Edward M. Kennedy Academy for Health Careers, was ordered held without bail at his arraignment in Brookline District Court Monday morning. A not-guilty plea was entered on his behalf Monday.
The other two male teenagers arrested in connection with the robberies, a 16-year-old and a 15-year-old from Dorchester who are 10th-graders at the same high school as Milton, are scheduled to appear in court Thursday, prosecutors said at Milton’s arraignment.
Police have charged each of the teenagers with two counts of armed robbery in connection with the robberies reported Sept. 25 and Oct. 5.
Detectives have recovered video surveillance of possible suspects filmed nearby and around the time when each of those daylight robberies occurred.
Two other similar robberies were reported Sept. 23 in the early morning hours and on the night of Oct. 9.
“The other two robberies are still under investigation,” said Lieutenant Philip Harrington of the Brookline police.
In each of the four cases, students or recent graduates of BU reported being robbed at gunpoint by two or three males in their teens or early 20s, authorities have said.
Harrington said no gun has been recovered.
Smartphones, cash, wallets, laptops, backpacks, keys, and credit and debit cards have been stolen. No injuries were reported.
Judge Robert P. Ziemian scheduled a dangerousness hearing for Milton for Thursday.
When the judge ordered Milton to be held without bail, some in the courtroom let out gasps.
After the arraignment, about a dozen people huddled in the lobby, some crying, others offering consolation.
Milton’s lawyer, Robert L. Sheketoff, declined to comment.
The robberies put the university community on edge and altered some students’ routines.
Increased police patrols continue in the area, BU spokesman Colin Riley said.
“We still urge members of the BU community and other people traveling through the area to stay alert and use caution,” he said.
On Wednesday, authorities released a video showing three potential suspects captured on a surveillance camera around when the Oct. 5 robbery was reported.
The day the video was released, BU announced it was offering a $10,000 reward for tips leading to an arrest and conviction. Riley declined to comment on the reward Monday.
According to court documents, a relative of one of the juveniles was watching a news report on the robberies Wednesday and recognized the teenager.
The suspect turned himself in to police Thursday, accompanied by his lawyer and the relative.
On Friday, high school administrators identified the teenagers when police showed them the video.
Milton was arrested at the school, and the other juvenile later turned himself in to police, accompanied by his lawyer and relatives.
The same day, a robbery victim identified, through police photographs, the teenager who pointed a gun at him as the 15-year-old, who wears braces.
The juveniles’ lawyers could not be reached for comment. A prosecution spokesman declined to comment about the juvenile cases.
