Portuguese national Orlando Silva, 42, had escaped from a mental health facility on Uxbridge Road, Southall, where he was detained under the Mental Health Act.
He ran away from the unit earlier this month on Wednesday, 6 January, at around 7pm.
Last week UK police reiterated an appeal for information on the man’s whereabouts, saying “anyone who sees him should not approach him but call police on 999 in an emergency or 101.”
The Metropolitan Police service said “Mr Silva suffers from schizophrenia and with no access to medication may be a danger to himself and others.”
Orlando Silva was found last Thursday morning, 21 January, and taken back to the facility.
