Nigerian police say a diplomat from Sierra Leone who was abducted last week has been freed, but it is not clear whether any ransom was paid to secure his release.

Police spokesman Don Awunah told reporters Wednesday that Sierra Leone's deputy high commissioner to Nigeria, Maj. Gen. Alfred Nelson Williams, was found in sound health and has been reunited with his embassy in Abuja.

Neither the police nor the Nigerian government gave details of how the diplomat was freed.

Nigerian workers at the embassy had said the abductors were demanding $40 million for his release.

Williams was abducted on Friday while traveling to Kaduna, a northwestern state of Nigeria, to attend a military parade. He was abducted along a major highway well known for armed robbery and abductions.
