An “emotionally disturbed” woman who allegedly attacked two Boston EMTs this week — stabbing one multiple times and pepper-spraying the other — is also being eyed in a recent bomb threat at the Martha’s Vineyard Airport.

Julia Tejeda was arraigned Thursday on charges including assault with intent to murder, assault and battery with a dangerous weapon, and assault and battery on a public official in connection to the attack, local station WHDH reported.

Now authorities are digging into whether she was involved in the Tuesday airport threat that caused the airport to close for about three hours in the morning as a helicopter and K-9 swept the area, according to the station.

“We will absolutely be looking into how many encounters law enforcement had with this individual prior to this tragedy occurring,” Suffolk County District Attorney Rachael Rollins told the outlet. “If there is something we could have done differently, that is absolutely something I would want to know about.”

Tejeda’s brother declined to comment to the station about whether his sister was involved in the incident.

The paramedics were transporting Tejeda — who they picked up in East Boston — to Mass General Hospital for a psych evaluation when she became “unruly” and set upon them, according to police.

In the Wednesday attack, Tejeda allegedly first stabbed the female EMT — leaving her with wounds so severe that she required surgery, police said at the time. Then she went after her partner, spraying her with pepper spray or mace, authorities said.

She allegedly claimed she attacked the EMT because she was taking her to the hospital and “was making me uncomfortable,” court documents obtained by the local station reveal.
