No arrest in marathon bombings: Boston police

Contrary to earlier reports, no arrest has been made in the twin marathon bombings that killed three people and injured more than 170, Boston police said Wednesday afternoon.

FBI and police had scheduled a news conference Wednesday to provide an update on the situation, but it was cancelled.

Earlier, CNN had said the suspect was identified through two surveillance videos, one of which reportedly shows the suspect planting one of the bombs. And The Canadian Press reported that the suspect was in custody and would be appearing in federal court.

On Tuesday, law enforcement officials said they recovered forensic evidence that suggests the two explosive devices which ripped through participants of the Boston Marathon on Monday may have been inside heavy black nylon bags.

Investigators who found pieces of black nylon at the scene suspect the bombs used in Monday’s attack were in dark-coloured bags that would have been heavy to carry, FBI special Agent in Charge Richard DesLauriers said at a joint law enforcement news conference on Tuesday.

Officials also suggested a pressure cooker stuffed with gunpowder and shrapnel may have caused at least one of the blasts.

The FBI’s DesLauriers said the investigation is in its infancy and “at this time there are no claims of responsibility. The range of suspects and motives remains wide open.”

Law enforcement officials have sent the blast evidence to the FBI laboratory in Quantico, Va., for analysis, DesLauriers said, adding that assistance from the public will be crucial in identifying the bombing suspects.

“Someone knows who did this,” DesLauriers said, asking the public to alert law enforcement if they witnessed any of the following activity. “Any individual who expressed a desire to target the marathon, suspicious interest in researching how to create explosive devices, the noise of explosions in remote areas prior to yesterday which may have been used as tests by those responsible for these acts.”

DesLauriers said members of the public and business owners near the blast sites have shared video footage captured just before and after the explosions, and that digital video analysts are now analyzing the material.

An official with the Bureau of Alcohol, Tobacco, Firearms and Explosives said at Tuesday’s news conference that other evidence recovered so far also include debris taken from nearby rooftops and embedded in the sides of buildings.
