MANILA, Philippines ? Authorities released on Thursday artist sketches of three suspects believed to be responsible for the kidnapping of Irish priest Fr. Michael Sinnott in Pagadian City last Sunday.

This came as the local government appealed to the abductors to be mindful of the health of the 78-year-old priest.

Allan June Molde, spokesman of Task Force Sinnott, described the three suspects as follows: the first about 5?2? to 5?3? in height, 22 years old, brown complexion, and slim built; the second between 5?2? to 5?4? in height, between 25 to 27 years old, brown complexion, black hair, and medium built; the third is said to be between 30 to 35 years old, around 5?6? in height, with dark complexion and black hair.

Molde said the sketches were derived based on witness accounts of the incident.

He added that authorities have yet to identify which group these men belonged to or if they were associated with either the Abu Sayyaf Group or the Moro Islamic Liberation Front.

Molde said authorities were worried on the health of Sinnott, who reportedly recently underwent heart surgery.

Sinnott, a Columban missionary, was abducted Sunday night. No group or individual has yet claimed responsibility on the abduction. No demand or ransom has also been made at this time.

Bishop Emmanuel Cabahar was the designated negotiator for Sinnott?s release. However, no group has contacted the bishop as of this time, Molde said.

Meanwhile, the crisis management committee and the task force are studying the possibility of providing monetary rewards for any information that will lead to the immediate rescue or release of Sinnott, Molde added.
