Guinea ex-army chief arrested after attack - police source

CONAKRY, July 19 (Reuters) - Guinean authorities arrrested a former head of the army on Tuesday after President Alpha Conde escaped a rocket and gunfire night-time attack on his residence, a police source told Reuters.

"General Nouhou Thiam has been arrested and taken to police headquarters," said the senior source, without giving further details.

Separately, police and army sources said a second soldier, who was a former member of Conde's presidential guard, had also been arrested. (Reporting by Saliou Samb; Writing by Mark John; editing by David Lewis)
