During the Beijing Olympics, sports venues had to conduct security checks on spectators. Suppose that at the start of the security check, there were already several spectators waiting outside the venue. After the security check started, the number of spectators arriving at the sports venue increased at a fixed rate. Also, assume that the efficiency of each security staff member is the same. If 3 staff members are used for the security check, it takes 25 minutes to complete the check for those waiting outside, allowing newcomers to be checked upon arrival; if 6 staff members are used, the time is reduced to 10 minutes. To complete the above process in no more than 5 minutes, at least how many staff members need to be arranged for the security check?
