Face operation after machete attack

Miriam Greene, 59, originally from Reading, Berkshire, had a steel plate inserted in her jaw after she and her husband were attacked in their home on the island on Saturday.

Peter Greene, 65, who was also seriously injured in the incident, remains in a medically-induced coma, hospital officials said.

Doctors are waiting for his condition to stabilise before considering surgery.

The couple have reportedly lived in the town of Bacolet along Tobago's southern coast off-and-on for 10 years.

Detectives said they had questioned several people in the area but there were no suspects.

Following the attack the Foreign Office updated its advice for travellers to Trinidad and Tobago, saying: "You should be aware that there are high levels of violent crime, especially shootings and kidnappings. British nationals have been victims of violent attacks, particularly in Tobago where law enforcement is weak."

According to local reports the pair are being treated at the Eric Williams Medical Complex on Trinidad.

Tobago police superintendent Nadir Khan described the attack on the Greenes as "another serious attack on tourists".

Bacolet is about seven miles from where Swedish couple Anna Sundsval, 62, and Oke Olsoon, 73, were killed last year in a similar attack. Authorities detained one person in that case but released him for a lack of evidence.
