>The police found placards and “items which at the time they had reasonable grounds to believe could be used as lock-on devices,” according to the statement, and arrested six people “on suspicion of going equipped for locking on.”

After the police investigation failed to prove that anyone had intended to use the straps to lock on, all six had their bail canceled and no further action would be taken against them, the police said.
