MDC Alliance legislator for Harare West, Joanna Mamombe and two party youth activists - Cecilia Chimbiri and Netsai Marova - reported missing from Wednesday, have been found with injuries from beatings by suspected state security agents.

The three went missing Wednesday following their reported arrests by police in Harare, moments after they led an anti-government protest in Warren Park high density suburb some five kilometres outside the city centre.

"We are concerned that three female MDC officials remain missing after they were reportedly arrested in Harare yesterday.

"Concerned to hear lawyers still not told of whereabouts of female MDC officials reportedly arrested in Harare," said the embassy.

The disappearance of the three and their eventual dumping along the road is consistent with that of firebrand former doctors association leader Peter Magombeyi who went missing for days last September only to emerge dumped by the roadside few kilometres outside Harare.
