Drone seen at Channel Tunnel
The BBC has been told that a drone, assisted by police search teams, was deployed around the Channel Tunnel facility in Kent yesterday afternoon.
Drones are regularly used to track migrants at sea - and there's been no official confirmation that operation definitely related to Khalife.
But, at the same time, it could have been a complement to the enhanced lorry checks at the border.
Accounts of searches don't tell us for sure where Khalife is hiding - but they indicate the scale of the resources that Scotland Yard and its partners are prepared to throw at capturing Britain's most wanted man.
Rowley won't confirm if notebooks found in Khalife's cell
Here's a bit more from Met Commissioner Sir Mark Rowley, who spoke to LBC earlier.He refused to confirm whether notebooks were found in Daniel Khalife's cell in Wandsworth prison after he escaped on Wednesday.
During the phone interview, he also said he couldn't comment on how the straps Khalife used to attach himself to the underside of the delivery van were made.
