Missing 12-year-old Edilsy Roca safe in police custody, criminal investigation ongoing

No arrests have been made at this time, police said.

Police in Fort Myers, Florida, have canceled a missing child alert after 12-year-old Edilsy Roca was found Friday evening.

"The child is safe," Fort Myers Police Department tweeted, hours after it said detectives believed Edilsy could be with her mother and her mother's boyfriend in Lehigh Acres, an area in Lee County, and that "she could potentially be in danger" if found in her mother's custody.

Police spokesperson Kristin Capuzzi told ABC News Friday night that Edilsy was in the custody of detectives. No arrests have been made, but a criminal investigation is ongoing, she said.

Capuzzi did not say where Edilsy was found due to the ongoing investigation. She had been last seen in Fort Myers at approximately 10:30 p.m. Monday walking in the area of Gardenia Avenue.

In its alert, police had released pictures of the child, her mother, Imilsy Medina, and the mother's boyfriend, Fabio Miguel Costa Araujo, on the Fort Myers Police Department Facebook page and urged anyone with information about Edilsy's whereabouts to contact the police.

Police had initially urged members of the public not to approach either Medina or Araujo but to contact police immediately.

It is unclear who reported Edilsy missing and when police were first notified.

A spokesperson for the Fort Myers Police Department told ABC News on Friday afternoon that no further information was available as it is an ongoing investigation.
