A suspect who is charged with lying to investigators of the Boston Marathon bombing will be closely monitored under "strict conditions."
Under terms proposed by his defense attorney and prosecutors Monday, Robel Phillipos, 19, will be confined to house arrest and ordered to wear an electronic bracelet, allowing authorities to track him day and night.
The conditions stipulate that Phillipos can't stay in his own home. Instead, he must report to "the residence of a third-party custodian," according to the proposal.
The joint motion, filed Monday morning in Boston's federal district court, requests that the bond for the college friend of accused bomber Dzhokhar Tsarnaev be set at $100,000. A magistrate agreed to the terms, WCVB reported.
Last week, Phillipos and two teens originally from Kazakhstan who attended the University of Massachusetts at Dartmouth were accused of helping Tsarnaev after he and his brother Tamerlan allegedly detonated bombs at the Boston Marathon on April 15.
An affidavit from an FBI agent said that Phillipos gave conflicting statements about visting Tsarnaev's dorm room in the days after the bombing that killed three people and wounded more than 260 others at the marathon's finish.
The charges against Phillipos don't allege that he played a role in planning the attacks. Instead, he's accused of misleading authorities, who interviewed him several times in the days after last month's bombing.
The Kazakh students -- Dias Kadyrbayev and Azamat Tazhayakov, both 19 -- were charged with conspiracy to obstruct justice, for allegedly dumping evidence related to the bombing they found in Tsarnaev's dorm room. An affidavit said they threw away a backpack, a laptop and fireworks that had been emptied of gunpowder.
They face additional charges related to violating the terms of their student visas.
When Phillipos first appeared in court last Wednesday, prosecutors maintained that he "posed a serious risk to flight," according to court documents.
But both sides have agreed on conditions that would spring Phillipos from jail.
"Since the initial appearance, the parties have conferred extensively and now agree that the court can fashion strict conditions of release that will reasonably assure the defendant's appearance at future proceedings," said the motion written by defense lawyer Derege Demissie and officials in U.S. Attorney Carmen Ortiz's office.
If convicted, Phillipos could be imprisoned for eight years and fined $250,000.
Both sides asked that Monday's probable cause hearing be pushed until May 16, to give them time "to confer about how this matter should proceed."
Like Tsarnaev, Phillipos lived in Cambridge, Mass. Documents filed Saturday and reported by the Boston Globe revealed additional information about his personal life.
He's the only son of Genet Bekele, a domestic violence specialist with a master's degree from Boston University. Filings by his defense state that Phillipos is bilingual in English and Amharic, the official language of Ethiopia.
