The flight was heading to Los Angeles from Newark, New Jersey when it made an unscheduled landing at Chicagos OHare International Airport at 7:44 a.m. local time due to a potential security concern, a United spokesperson confirmed to HuffPost in a statement. More than 200 passengers were onboard.

The plane was evacuated and cleared by police, the Chicago Police Department said in a statement, which referred further questions to the FBI s office in Chicago. A representative there told HuffPost its office responded to the incident and determined there was no immediate threat to public safety or to the facility.
