DISTURBING details about the homeless man who allegedly prowled through a Walmart and stabbed 11 people have been revealed.

Bradford James Gille is accused of bursting into the Michigan supermarket and attacking shoppers on Saturday afternoon.

The 42-year-old suspect was arrested after a brave bystander whipped out a gun and demanded that the crazed alleged attacker drop his weapon.

He’s now facing nearly a dozen assault charges with cops accusing him of intending to murder the victims at the store in Traverse City, about four hours north of Detroit.

Gille entered the store at around 4:10 pm and hung around for nearly an hour before he started running around and stabbing people at random, the Grand Traverse Sheriff’s Office said.

Terrified witnesses have described hearing screams erupt from the sales floor and running through the bloody scene as they tried to evade the deranged attacker.

Cops said that Gille used a “standard folding-style knife” with a 3.5-inch blade and released pictures of the blood-spattered weapon.

Gille was cuffed just three minutes after cops arrived at the scene with the help of citizens who stopped him at the entrance of the store, authorities said.

Eleven people aged 29 to 85 were rushed to the hospital after the mass stabbing, and some were in critical condition.

As of Sunday, 10 of the victims were still getting treatment, but all of them are expected to survive, according to medical officials.

One shopper, Julia Martell, said that she was browsing the canned foods aisle when she heard yells and saw a man running through the pharmacy area, the New York Times reported.

She remembers seeing the attacker erratically shoving and stabbing people before suddenly changing course and heading directly for her.

Martell quickly sprinted away from the man and watched as he turned the other direction toward the entrance.

She said, “If anything, him not following me kind of scared me more because then you had no idea where he was.”

Martell described seeing “blood everywhere” when she was escorted out of the store, and saw a man lying on the ground.

BRAVE BYSTANDER

A viral video taken of the attack has captured Marine veteran Derrick Perry whipping out a gun and demanding the suspect to drop his knife in the Walmart parking lot.

Perry yelled out, “Drop it. Throw the knife now. Throw it away,” before the attacker finally complied and started backing away.

The brave Marine kept his gun pointed at the suspect until cops came up behind and cuffed him.

Perry was named by his daughter-in-law, who described him as a “true hero.”

“So proud of him for protecting so many today,” she wrote on a Facebook post.

Another witness, Michael Miller, described helping to stop the suspect after pulling his family to safety.

He walked in with his fiancée Julia Ling and their four children when screams rang out, NBC News reported.

Ling said that she threw their children behind a bread rack to hide them and watched in horror as the attacker stabbed one person in the produce aisle and another at the self-checkout.

The suspect noticed Ling and her children and lunged at them before Miller and others pushed him out of the building.

SUSPECT ARRESTED

Cops received a court order to arrest Gille before the stabbing took place, but it’s unclear what he was wanted for, the Emmet County Sheriff’s Office said in a statement.

According to the order, Gille has no known address and is homeless. He also has a history of assault incidents and “controlled substance violations,” Grand Traverse County Sheriff Michael D Shea said.

Although it’s unclear why Gille allegedly carried out the attack, officials are looking to pin him with a terrorism charge.

They believe the attacker was seeking to strike fear into an entire community rather than target specific individuals, Grand Traverse County prosecutor Noelle Moeggenberg said.

In a statement, Walmart said, “violence like this is unacceptable.”

“Our thoughts are with those who were injured and we’re thankful for the swift action of first responders,” the company said.
