Boston police officials have offered support staff to law enforcement responding to the Orlando, Florida, nightclub massacre.
A BPD spokesperson said the offer to send down personnel who directly dealt with the marathon bombings and can help council in a crisis situation has not been accepted yet.
Forty-nine people were killed early Sunday morning when a gunman sprayed a helpless crowd at Pulse, a popular gay nightclub, making it the deadly mass shooting in modern U.S. history. Fifty-three others were injured in the rampage.
Meanwhile, police officers have increased their patrols around LGBT clubs, restaurants and stores.
FBI agents with the Boston field office who led the investigation into the marathon bombings will not be sent to Orlando as of now.
A spokesperson said agents are coordinating with federal, state, local and community partners, and will be sharing information and intelligence as expected.
Massachusetts state police said on Sunday that the gunman, identified as Omar Mateen, called 911 during the shooting and referenced the Boston Marathon bombers.
Tamerlan and Dzhokhar Tsarnaev killed three people and injured more than 260 in the April 2013 attack near the Boston Marathon finish line.
