Each attack targeted people walking their dogs.

Ald. Andre Vasquez (40th) and the victims told CBS 2’s Tara Molina that a man was behind the attacks. Police were still trying to locate the man on Thursday.

Katie Lyons told us she was walking her dog on Ashland Avenue, looking up to smile at the man passing by. It was then that she saw the cup in his hand and the look in his eyes.

“The look of rage on her face – and just the look of her eyes,” Lyons said. “He had a large mug in his hand, and just as he walked past me he threw the contents in my eyes. And I screamed for help, just because my eyes were burning and I couldn’t see, and I dropped my phone.

Lyon rushed home.

“I knew I had to rinse my eyes, and no one came to help me,” she said.

Lyons at first wasn’t sure what was being thrown at him. She said it didn’t click until she asked first responders.

“They said I smelled like urine,” Lyons said.

Lyons was seen by her ophthalmologist and examined at the hospital. Fortunately, she is doing well.

But she is not the only one.

“He chased me, then he threw the urine at me and got the back of the coat,” said a woman named Sue.

Sue was attacked last week – also while walking her dogs.

She is still shaken up and uncomfortable sharing her full name.

“He’s been threatening for a long time,” Sue said.

In a bizarre twist, Sue said the man who attacked her actually went to the police station himself to file a complaint against her – claiming that she unleashed her two dogs on him.

“He saw the two witnesses and I think he was trying to get ahead,” Sue said. “It usually attacks at night.”

Sue followed up with the police and asked them why he had not been taken into custody.

“The policeman called me back and said, ‘He told us this story, so we let him go,'” Sue said.

Sue said police let the man go without following up on two witnesses to his attack who shared information with them. Police do not comment on this claim.

“The police claim that I am the only one who filed a police report – and I know it’s true,” Sue said. “I don’t know why it took them so long to take action. “

We have listed the three most recent incidents reported by Ald below. Vasquez – on Ravenswood and Balmoral avenues, Ashland and Balmoral avenues, and Ashland and Rascher avenues.

The attack targeting Sue, 48, occurred on Ravenswood and Balmoral avenues at 8:26 pm On December 7, police said the man threw a cup of urine at Sue while she was walking. her dog, which hit her face and body. This incident is classified as a simple battery.

A witness reported that another attack in the 5400 block of North Ashland Avenue occurred at 2 p.m. on December 30. In the incident, a woman was walking two dogs when someone attempted to throw an “unknown substance” but failed, police said. This incident is qualified as a simple assault.

No police report has been filed for the incident in which Lyons was targeted, which also occurred on Ashland Avenue.

Again, these are just the most recent incidents. Ald. Vasquez said he believed the attacks began during the summer and is now working directly with Chicago Police.

“We have neighbors in the neighborhood with guide dogs. We don’t want this to happen to anyone, but God forbid, it happens to someone who needs their service animal, ”said Vasquez. “We want to make sure this is dealt with quickly and that we get a resolution quickly. “

Vasquez said some of the attacks go unreported.

“They followed some of the people who emailed us,” Vasquez said.

Chicago Police said no one was in custody in the attacks.

“My hope is definitely this man gets some help,” Lyons said. “I’ve been working in psychiatry for 30 years, and you know, I really think he’s a danger to other people.”

Chicago police say this is still under investigation.

“We want to make sure that the DPC investigates, but also to identify the person to see if they are ready to accept mental health support,” Vasquez said.
