Turkey arrests Tera president after 12% Borsa Istanbul slide

Turkish authorities arrested the president of Tera, an investment firm, following heavy losses in its funds amid a 12% drop in the Borsa Istanbul All Shares index since last week. The arrest signals potential regulatory or legal fallout from the market decline, though details on the firm's exposure and charges remain unclear. This adds to investor uncertainty in Turkish markets, already pressured by the sharp equity selloff.
