After the devastating series of suicide attacks on Paris last year where 130 died, a similar plot is a `natural next step` for the terror group, he said.
Warning: Scotland Yard Assistant Commissioner Mark Rowley, pictured, has said the terror group is `trying to build bigger attacks` - and has its eye on the UK
Last November Mr Rowley admitted a suspected jihadi is being arrested every day to prevent a Paris-style terror attack.
He also revealed officers are holding known extremists for `anything we can` to `disrupt` potential terror plots on home soil.
Mr Rowley also revealed Britain had officers in France and Belgium after the attacks and was `harvesting information` about ISIS terrorists who killed 130 in Paris `to prevent attacks` in the UK.
