The FBI says they have no suspects nor anyone in custody over the deadly Boston blasts. Police are calling on witnesses to assist the investigation which has been called “the most complex crime scene” in the history of the Boston PD.
Speaking at the briefing led by the FBI and Boston city authorities the morning after the tragedy, The FBI said it's still seeking public communication, calling for witnesses to come forward.
“We are processing the most complex crime scene in the history of our department,” Police Commissioner Edward Davis said.
People who captured amateur photos and videos are being asked to submit their footage as it might help with the investigation into the double blasts which have killed three and left more than 170 people injured.
"We have received voluminous tips over the last 18 hours since the incident," FBI special agent in charge, Rick DesLauriers said.
The police gave no details on the going investigation.
Police are searching the 26.2 mile route of the race. Currently the crime scene has been scaled down  to12 blocks. FBI special agent in charge, Rick DesLauriers, said that there is currently “no known physical threat."
Police called on citizens to be patient as they will see a "continued, heightened police presence".

Investigators have searched an apartment in the Boston suburb of Revere, which police confirmed to be connected with the blast probe. But early reports of a detained suspect were later said to be false.
Authorities gave no details on the search. However, investigators were seen leaving a building there early Tuesday carrying brown paper bags, plastic trash bags and a duffel bag, AP reported.
Officials declined to comment on the suspects. When asked if there was anybody in custody, Police commissioner Ed Davis said "No-one's in custody."
The FBI special agent DesLauriers also declined to comment saying he is “not going to say who might or might not be in custody right now."
Earlier on Tuesday reports said police are seeking a suspect in the deadly Boston blasts described as a “darker-skinned or black male” with a backpack, media reports. They are also looking for a yellow van.
The suspect, who is said to possibly have a foreign accent, was seen trying to enter a restricted area five minutes before the first explosion, CNN reported.
As he was not allowed to do so, the man reportedly walked away and pulled his sweatshirt hood over his head.
There is also speculation circulating on the internet regarding a picture of what appears to be a man walking on the rooftop of a building overlooking the finish line, as the dust from explosion of the second bomb rises several hundred meters away.
Speaking at the press conference Massachusetts Gov. Deval Patrick stressed that “only two explosive devices were found yesterday”, rejecting reports that earlier suggested five explosives were found. The devices were triggered 12 seconds apart in the late hours of the race, when most of the top runners had finished and ordinary participants were completing the event.
However, investigators refused to provide information on the nature of the explosives. FBI special agent in charge DesLauriers declined to comment on the nature of the device.
When asked about a bomb placed in a trash can, Police commissioner Ed Davis said there was no evidence of that.
According to a person close to the Boston Marathon investigation, the explosives were in 6-liter pressure cookers and placed in black duffel bags, AP reports. The person, who spoke on the condition of anonymity, said investigators have some of the bomb components but did not yet know what was used to set off the explosives.
The Massachusetts General surgeon, who also spoke to the media, said that the shrapnel was consistent in size, and included nail-like fragments, he added that "most of [the metallic fragments in the patients] were in the bomb."
"There were people who had 10, 20, 30 of them in their body," he said.
