A 43-year-old man has been arrested over allegations he posted pictures of a Grenfell Tower victim on social media.
Images were posted of what appear to be a partially-covered body following the fatal blaze in north Kensington, west London.
At least 12 people are known to have died as fire ripped through the 24-storey building in the early hours of Wednesday morning.
The Metropolitan Police said a man was arrested on suspicion of sending malicious communications and obstructing a coroner.
Officers confirmed the arrest relates to the fire at Grenfell Tower and the man is in custody at a west London police station.
A council has admitted it received complaints over the refurbishment of a west London tower block which has been ravaged by a deadly fire, after an action group said its warnings fell on "deaf ears" when it highlighted safety concerns.
