Four inmates escaped a south Louisiana jail over the weekend and two were still missing Tuesday, authorities said.

Authorities were unaware that four inmates had escaped until a phone call tipped them off, the Tangipahoa Parish Sheriff’s Office said Monday.

The inmates escaped in pairs — the first on Saturday afternoon and the second on Sunday, said Deputy Chief Jimmy Travis at a news conference, WVUE-TV reported. Travis said all four broke through a corroded piece of chain-link fence, crawled under an 8-inch (20-centimeter) gap in a wall, and scaled two razor-wire fences.

Jail authorities learned of two of the escapes Sunday afternoon when a tipster reported seeing two of the inmates at a relative’s house looking for a place to stay.
