CHICAGO -- Authorities in Chicagoland are urging residents to report suspicious activity and packages following the explosion in New York City this weekend.
Chicago and Cook County officials issued a joint statement Sunday stressing the importance of the "If You See Something, Say Something" anti-terrorism public awareness campaign.
You can report non-emergency suspicious activity by calling 855-RPRT-2-S4, the official local number of the campaign.
"When you see things that look suspicious, just call the police," Chicago Police Supt. Eddie Johnson said. "We are encouraging our officers to also be more vigilant and observant in their day-to-day activities."
Johnson also said the Chicago Police Department has been in touch with police in New York about the explosion, and at this point, the incident has no connection to Chicago or international terrorism.
There were 29 people hurt in Saturday's explosion in New York, but most of their injuries are minor. New York police continue to investigate the incident.
