In the on-camera statement, Head of Counter Terrorism Policing Assistant Commissioner Laurence Taylor says that "extensive searches have taken place at an address in Rotherham", where the 28-year-old white British man was arrested.
He says there are "multiple lines of inquiry" that police are "pursuing expeditiously, including digital forensic examinations".
Taylor says he wants to remind the public that investigations like this are "complex" and "new information can emerge".
More information will be released when it is available and appropriate, he says.
