A good Samaritan who tried to help a lost tot find her family — was rewarded with a beating when the girl’s father and bystanders mistook him for a kidnapper, police said.

The Florida man, who was not identified by authorities, was trying to help a 2-year-old separated from her parents while at a baseball game in the Southwest Sports Complex in Lakeland, FL on Saturday.

Her parents “feared that the citizen was attempting to kidnap the child,” according to the Lakeland Police Department, ABC reported.

Bystanders who saw the man walking towards the parking lot with the child alerted her parents, who feared the worst.

“I saw this man with my daughter in his hands walking towards the parking lot. What would you do?” the father asked. “I wanted to kill him,” he told WFLA.

The father said he and three other men found the so-called-kidnapper and that he punched him repeatedly, while one of the other men grabbed the child.

“When I got there I just swung on him,” the father said. “I thought he was trying to take my daughter.”

The family then made sure the man, who was identified as a father and local businessman, got an additional slamming on social media, posting his photo, name, and place of work online and referring to him as a child predator.

Lakeland Police determined that the man was not trying to kidnap the child, following an investigation.

The man has opted against pressing charges against the family, who still doesn’t believe he’s innocent.

When asked by WFLA if the he bought the man’s version of events the father responded, “No. Hell no I don’t. Not at all.”
