Bloomington police Chief Jeffrey Potts said during a news conference that the boy fell almost 40 feet after a man who apparently didn't know the boy or his family threw him off the balcony Friday.
Landen's family launched a GoFundMe page to cover what is said to be "immense" medical and rehabilitation costs, and on Sunday a family friend shared an update about the little boy's recovery.
More than $USD377,000 ($AUD526,000) has been raised on the family's GoFundMe page to the boy who is being described as "the sweetest kindest five-year-old you will ever meet".
"The child did suffer significant injuries", Police Chief Potts said during the press conference.
The post also said the boy, who is being treated at Children's Hospital Minneapolis, will need multiple surgeries "to try to get back to a normal life for a young, vibrant boy". Because the family has asked for privacy, authorities are not yet releasing the name of the boy.
Aranda was arrested on July 4, 2015, after police said he matched the description of a man throwing things off the upper level of the Mall of America to the lower level, court records show.
24-year-old Emmanuel Deshawn Aranda has been charged with attempted murder after being chased down by police following the disturbing incident. In another case, Aranda assaulted a woman inside Twin City Grill after she refused to buy him food. He could be formally charged as early as Monday.
Police are on the scene of an incident at the Mall of America in Bloomington, Minnesota. Police still do not believe there was any connection between the family and Aranda. The child had fallen from the third level to the first.
Aranda's criminal record includes two convictions in 2015 for obstruction of the legal process/interfering with a peace officer, as well as convictions for fifth-degree assault, trespassing and damage to property.
Mall of America officials said any more information about the incident will come from police.
Aranda, whom police said took off running after the incident, was found inside the mall's transit station and arrested.
Despite the incident, Potts thinks the mall is still a safe place.
Police said the 24-year-old man is not known to the child, or the child's family. At one point, Aranda had a trespass notice banning him from the mall, but it was no longer in effect.
