Ryan Cleary, 19, of Wickford, Essex, was charged last month with five offences under the Criminal Law and Computer Misuse Acts, including an alleged hacking attack against Soca's website.
Mrs Gower said she was concerned because the style of the email was similar to that used by Muslim hacking groups who had previously attacked the EDL website.
Images posted to a Pastebin page suggest the hacking group accessed some sites by attacking the databases many companies use to catalogue and curate website content.
Earlier this week members of LulzSec and the larger hacker group Anonymous defaced the website of the News Corp-owned paper The Sun in retaliation for the phone-hacking and cover up that took place at its sister paper, the now-defunct News Of The World.
