A New York City police lieutenant was shot in the arm in the Bronx Sunday morning, about 12 hours after another officer was shot in the head while on patrol nearby, police authorities said.

The Sunday morning incident took place in the 41st Precinct in the Longwood neighborhood of the Bronx, where cops quickly cordoned off the streets and apprehended a suspect, who is believed to be connected to the previous night's shooting, multiple officials told ABC News.

Another officer was wounded in Sunday's incident. Both officers, who have not been identified, were rushed to a hospital, and their injuries do not appear life-threatening, according to police.

The neighborhood was rocked with violence Saturday night when a suspect allegedly walked up to a marked police vehicle and began asking for directions before opening fire at the officer, according to ABC News' New York station WABC.

The investigation was ongoing and New York City Police Commissioner Dermot Shea and Mayor Bill de Blasio were slated to provide an update later in the day.

"This vicious assassination attempt is the second one we’ve seen in 24 hours — and an attack on our NYPD officers is an attack on ALL New Yorkers," Mayor de Blasio tweeted. "This despicable hatred is an attempt to divide our city and undermine our safety. We cannot and will not let that happen."

Gov. Andrew Cuomo tweeted Sunday morning that he was horrified by the multiple attacks and promised to bring the suspect to justice.

"NY's law enforcement officers put their lives on the line every day to keep us safe. These attacks are heinous," he wrote.

Police say the officer wounded in Saturday's attack yelled once he saw the gun and put the police car into drive but was struck by a bullet in the neck and chin during the commotion. Officers were not able to return fire during the incident.

The officer's partner then immediately drove the injured man to Lincoln Hospital where he was being treated and is expected to survive. The officer has not yet been publicly identified but authorities have confirmed that he is an 8-year veteran assigned to the 41st Precinct and that he has known his partner since they were in middle school.

"Multiple shots were fired by the perpetrator at close proximity into the van," said Police Commissioner Shea during a press conference. "At least one, possibly two, shots struck the operator of the van. One struck him in the chin. One struck him in the neck narrowly missing the carotid region and it is a miracle that we are not here under worse circumstances."

Mayor de Blasio echoed the commissioner's sentiments during the same press conference.

"Our officer and his partner, under the most adverse possible situation, did everything right and thank God both of them are safe," said de Blasio. "But I want New Yorkers to be clear, this was an attempt to assassinate police officers."

The suspect in Saturday's shooting has been described as a 20-30-year-old man dressed in black with a black hat, and approximately 5'7" in height.
