Insufficient articulable grounds for a protective sweep where two armed men robbed a bank, and both had been detained prior to the sweep through the house.
Subsequent consent to search was tainted by the fruits of the sweep.
Court's instruction sufficient to cure in-court statement by police officer saying that the robbers had been identified to him by name by an informant.
Other hearsay harmless.
