A man wielding an ax was shot and killed by a security guard outside of a weed dispensary in Chicago on Labor Day, authorities said.
Police said the incident happened just after 10 a.m. in the 200 block of South Halsted, when a man got into a verbal altercation outside of a business with a 37-year-old man working security.
The man ultimately began swinging an ax at the security guard before striking him in the leg.
"A struggle ensued and the victim fired shots, striking the offender," police said in a statement.

The man with the ax was taken to Stroger Hospital, where he was pronounced dead. The man working security was taken to Northwestern Memorial Hospital in good condition, authorities said.
An investigation remained ongoing.
"This morning outside Zen Leaf on Halsted Street, an individual attacked a contracted third party security guard with a weapon outside the dispensary. Both individuals were taken to hospitals with serious injuries," the dispensary told NBC 5 in a statement.
The dispensary added that it will be closed for the remainder of the holiday as police continued their investigation.
Sources close to the investigation told NBC 5 the ax-wielding man may have been a disgruntled customer.
