An elderly man is in critical condition, after he was chopped repeatedly by a mentally ill man while in his garden.
A 33-year-old suspect was held and is in police custody.
Police said James Gajadhar, 77, a pensioner, went to the garden behind his home in Rio Claro at 3.30 pm on Wednesday to pick ochros.
About half an hour later, his wife got worried when he did not return and went to check on him.
She found her husband bleeding on the ground with gaping wounds on his body.
The woman sought help. Gajadhar was taken to the Rio Claro Health Centre, where he was treated and transferred to the San Fernando General Hospital.
A relative told Guardian Media yesterday that the pensioner was in a critical state and his loved ones were praying that he survives.
Officers from the Rio Claro Police Station are investigating.
