Authorities searched a Revere apartment and questioned two students from Saudi Arabia as part of the investigation into the Boston Marathon explosions.
Mohammed Bada, 20, told reporters Tuesday that he and his roommates, ages 22 and 19, are in the U.S. to study English.
When Bada arrived home late Monday night, he found officers surrounding his Ocean Avenue apartment, which he described as "scary, so scary."
"I was five hours with the police," Bada said. "I signed some paper to let them in."
Bada said authorities told him that his older roommate is being treated at Brigham and Women's Hospital with shrapnel wounds from the Marathon explosions.
The Boston Globe reported that the hospitalized student was questioned by investigators.
Law enforcement sources told Reuters that the student, who had been temporarily considered a "person of interest," would be cleared of suspicion because of evidence uncovered in the investigation.
CNN reported this afternoon that the student is not considered a suspect.
Boston Police Commissioner Ed Davis said no one had been arrested in connection with the explosions.
The third roommate's location was unknown. Bada would not tell reporters either of his roommates' names.
"Is my friend in action with this bomb? I don't know," Bada said in broken English.
When asked if he thinks his roommates were involved, Bada said, "No, I don't think so ... because they're good people."
Investigators removed items from the apartment, but Bada said he didn't know what was taken because he was not allowed inside during the search.
