The Speaker released the news…
UPDATE II: Met letter to Speaker (via Sophy Ridge):
“I write to inform you that on 2nd December 2014, Mark Pritchard MP was arrested at 6.14pm at Holborn Police Station in London by MPS officers. Mr Pritchard was questioned by police and released on bail later the same evening at 10.16pm. The matter is subject to further investigation and is sub judice at the present time.”
“We can confirm that a 48-yr-old man voluntarily attended a north London police station on Tuesday 2 December where he was arrested following an allegation of rape in central London. He has been bailed to a date in early January 2015.”
"You're not fucking royalty, Mr Speaker!" Mark Pritchard once said. Speaker put news of his arrest into the public domain.
