Police are warning Gold Coast residents after four instances of gunfire struck high-rises along Lake Shore Drive over the past month.
The most recent shooting happened Thursday morning in the 1100 block of North Lake Shore Drive, Chicago police said in a community alert.
Three other shootings occurred the morning of Feb. 11 on the same block.
In each case, someone fired a handgun and struck windows or the outside of buildings, police said. No injuries were reported.
Police did not disclose a suspect description or who may have been targeted.
Former mayoral candidate Bill Daley and his sister Patricia Daley Thompson Martino live in separate buildings within a block of the shootings, according to Illinois State Board of Elections and Chicago voting records.
Anyone with information was asked to call Area Three detectives at (312) 744-8263.
