Anchorage police are seeking a quartet of suspects, who are considered armed and dangerous, plus a person of interest in the beating of a man who was dropped off critically injured at a local hospital earlier this week.

Three men and a woman – Macauther Vaifanua, 28; Faamanu Vaifanua, 27; Jeffery Ahvan, 29; and Tamole Lauina, 21 – are all charged with the kidnapping of 34-year-old Abshir Mohamed. The men are also charged with first-degree assault.

Mohamed was dropped off at a hospital shortly before 6 p.m. Sunday, in a case about which police had initially released few details.

Police spokesman MJ Thim said the incident was related to a warrant service conducted Tuesday evening by SWAT officers on Cimarron Circle. He added in a statement that Mohamed had last been seen Sunday afternoon by his girlfriend.

“Between the time his girlfriend last saw him and the time he showed up at a hospital, Mohamed was bound and beaten inside the garage of a residence in the 6500 block of Cimarron Circle,” Thim wrote. “He was then placed inside an animal cage, still bound, and dropped off at a local hospital. He was still inside the cage.”

Police described Mohamed’s kidnapping as a targeted crime and “not random.”

Thim said Mohamed had been dropped off at the hospital by a driver, who stayed at the scene and cooperated with officers. He declined to discuss what the driver told police, but said no charges have been filed against that person.

It wasn’t yet clear why Mohamed was kidnapped and beaten, Thim said. Police have not been yet able to speak with Mohamed at the hospital.

“We’re still trying to determine the relationship between the victim (and) the suspects,” Thim said. “Detectives are still trying to determine how everything is connected.”

Police said in a second statement that they were also seeking an unidentified person of interest, seen in the photo below, who "was at the residence during the assault."
