RIO DE JANEIRO (Reuters) - Work restarted on the Olympic beach volleyball arena on Wednesday, four days after it was halted because of a missing permit, officials in host city Rio de Janeiro said.

Construction on the temporary structure ground to a halt on Saturday but resumed after new paperwork was filed, according to the city's Environment Secretariat.

Although the environmental licenses are still being reviewed, officials guaranteed the venue on Rio's Copacabana beach will be finished in time for the start of South America's first Olympic Games on Aug. 5.
