Officer Hannah Warren, a spokeswoman for the department, said police could not immediately confirm the numbers but would be conducting a news conference later Sunday.
Chicago Police Superintendent Eddie T. Johnson said during a news conference that police arrested 46 people over the weekend for gun charges and that they seized 60 guns over the weekend alone.
Two people were killed and 28 were wounded between midnight and 3 a.m., including at least 13 teenagers. "Right now, Chicago has one of the worst clearance rates for homicides and other violent crimes among America's major cities", mayoral challenger Paul Vallas said.More news: Cleveland Browns trade former Baylor WR Corey Coleman to Buffalo Bills
At least 34 people were shot across Chicago over a 24-hour period beginning at 10 a.m. Saturday, police said Sunday.
Johnson was more direct in his reaction to this weekend's bloodshed, angrily lashing out at the shooters. Somebody knows who did it.
He said "the city isn't on fire", but emphasised the need for community members to identify the individuals causing the violence.More news: City back in the groove as Aguero ruins Sarri’s Chelsea bow
"An offender or some type of rival gang sees a large group of people. and they shoot into a crowd, no matter who they hit", he said. Johnson echoed that, saying there are often people who know who pulled the trigger but don't go to police.
It's good that their Police Chief is finally willing to stand in front of reporters and admit that they've got a gang problem, but that doesn't do anything to address the underlying issues. They hold me accountable, they hold the mayor accountable, they hold the city council accountable - where's their accountability?
Former Police Supt. Garry McCarthy, fired by the mayor in 2015, accused Emanuel of continually ignoring violent crime on the South and West sides.
But it's not just conservatives who are outraged. CPD representatives said Sunday that they plan to focus their resources for the evening on neighborhoods where retaliation seems likely.More news: RBI hikes key rate 2nd time in two months
The gun violence has been the subject of two high-profile protests this summer, as demonstrators temporarily blocked major expressways to demand more economic investment and job opportunities in poor communities. Before the weekend's surge, they credited it with declines in homicides and shootings from previous year.
