Chicago police are investigating a string of robberies involving two modes of transportation in the city, as well as the robbery of a delivery driver on the same street as two other heists.

Police are probing robberies at the CTA Red Line station at 63^rd Street, as well robberies in taxis and ride shares in the Grand/Central area of the city.

In the robberies at the Chicago Transit Authority station in the Englewood neighborhood, the offenders approached victims and hit them as they stole property.

The CTA station robberies occurred at:

• 10 a.m. Jan. 5
• 9 p.m. Jan. 25
• 7 p.m. Jan. 28
• 7 p.m. Jan. 30

The offenders were described as one to three black males, ages 16-20, 5 feet 5 inches to 6-0, and 150-200 pounds.

In the Grand/Central robberies — all on the 1200 block of North Mason Avenue — one or two offenders were passengers in a taxi/ride share vehicle. As the offenders arrived at the location in the 25^th Police District and exited the vehicle, one of the offenders displayed a handgun.

In another Grand/Central robbery, an offender ordered food and upon the victim arriving in his vehicle, the offenders robbed him.

The robbers have demanded money, cell phones and other valuables from the victims before fleeing on foot.

The 25^th District robberies have been at:

• 9:56 p.m. Feb. 11
• 12:10 a.m. Feb. 12

The two offenders were described as black men, 20-25 years old and 190-200 pounds. One is described as 5-6” to 6-0. The other is described as 6-0 to 6-3.

In two of the Mason Avenue robberies, an offender was wearing a ski or surgical mask.

Police offered the following tips to avoid being robbed and how to react, if a robbery victim:

• If confronted by offenders, attempt to remain calm.
• Install tracking software and security locks on your cell phone.
• Keep electronics and wallets secure in a front pocket.
• Be aware of your surroundings.
• Report suspicious activity immediately.
• Remember any unique physical characteristics (scars, limp, acne, teeth, etc.).
• Never pursue a fleeing assailant. Provide the information to police.
• Dial 911 immediately and remain on the scene, if possible.
• If approached by a witness to the incident, request contact information.
