Eight members of the Milwaukee Police Department have been disciplined in connection with the arrest of the N.B.A. player Sterling Brown, who in January was subdued with a stun gun over a parking violation.

The department announced on Friday that three officers would receive unpaid suspensions. Those officers and five others will receive policy review instruction and remedial training in professional communications, the department said.

The most substantial punishment, a 15-day suspension, went to a police sergeant who has served for more than 11 years. Another sergeant, with 12 years of service, received a 10-day suspension. An officer with two and a half years on the force received a two-day suspension.
