News reports quote American officials as saying police in Zambia have detained a man whom U.S. authorities suspect of involvement in the deadly July 7 bombings in London.

The reports Thursday by CNN Television and The Los Angeles Times newspaper identify the man as Haroon Rashid Aswat, a British citizen of South Asian descent in his early 30s.

The reports say U.S. and Zambian officials are holding talks to determine where to prosecute Mr. Aswat.

Reports say Mr. Aswat came to the attention of U.S. authorities in connection with alleged attempts to set up an al-Qaida training camp in the western United States several years ago.

Separately, British police are still conducting a nationwide manhunt for the three remaining fugitive suspects in last week's failed bomb attacks on the London transit system. Police arrested a fourth suspect Wednesday.
