BUENOS AIRES, March 19 — Four footballers of Argentine premier division club Velez Sarsfield were provisionally detained yesterday in an investigation into allegations they raped a woman in a hotel room this month, the plaintiff’s lawyer said.

The four — Uruguayan Sebastian Sosa, Paraguay’s Jose Florentin and Argentines Braian Cufre and Abiel Osorio — were ordered held for 48 hours until a judge decides whether they should remain under arrest pending the investigation.
