INDIANAPOLIS (AP) — The FBI has joined Indianapolis police in investigating the disappearance of an 8-month-old baby.

FBI spokeswoman Chris Bavender confirmed Wednesday the FBI is assisting police with the investigation into the whereabouts of Amiah Robertson.

Police on Tuesday issued a statewide Silver Alert for the baby who was first reported missing Saturday by her family. Police said she is “believed to be in extreme danger and may require medical assistance.”

The Silver Alert was cancelled as of Wednesday, March 20, at 10 p.m. “due to very few tips coming in on the Silver Alert hotline,” according to Indianapolis Metropolitan Police Department. They’ve asked people with credible tips to call the missing persons division at 317-327-6160 or the Homicide Office at 317 327-3475. Numerous tips have also been submitted to police via social media.

Police say Amiah’s family initially told investigators she had last been seen Thursday and “was not believed to be in danger.” That last sighting later was updated to Saturday.

Police executed a search warrant Tuesday at a house on the west side of Indianapolis where Amiah was believed to have been left with a baby sitter. On Wednesday, police searched an area near Eagle Creek and I-70 where items that might be connected to the case were found.
