Fire crews responded to a fire outside of an apartment door on the third floor of this Cedarwood Apartment building Sunday shortly before 4 a.m. The fire was just the recent in a string of 10 suspected arsons in the area.

A fire early Sunday morning bears similarities to a string of suspected arsons reported by public safety officials during the past couple weeks in Lawrence.

Fire officials, who have sought public assistance, have released little information about the cases. They have said they suspect arson in fires reported since Oct. 19 in an area from 23rd Street south to 25th Street and from Iowa Street east to Naismith Drive.

Sunday’s fire was reported shortly before 4 a.m. at an apartment complex at 1703 W. 24th St., according to Mike Frizzell of the Journal-World’s reporting partner, Operation100 News. The building had filled with smoke and there were reports of a “bag of chips” on fire in a third floor hallway. Crews quickly extinguished the fire, and no injuries were reported.

On Monday, Fire Chief Mark Bradford declined to provide more information about the fire but did release a fire report, which categorized the fire as an arson.

Bradford did not say whether officials believe Sunday’s fire was related to the string of suspected arsons. He has declined to provide information on any of the suspected arsons.

The Journal-World filed an open records request last week for all fire reports in Lawrence since Oct. 19. Those reports — provided at a cost of $110 — detailed nine fires that fit a similar pattern.

Here are the times, dates and locations of those nine cases:

• 11:15 p.m. Friday, Oct. 19, 2340 Murphy Drive.

• 3:58 a.m. Wednesday, Oct. 24, 2429 Redbud Lane.

• 1:49 a.m. Saturday, Oct. 27, 1732 W. 24th St.

• 9:20 p.m. Monday, Oct. 29, 1722 W. 24th St.

• 1:35 a.m. Tuesday, Oct. 30, 1733 W. 24th St.

• 3:13 a.m. Friday, Nov. 2, 1504 W. 24th St.

• 4 a.m. Sunday, Nov. 4, 2350 Ridge Court.

• 7:03 p.m. Tuesday, Nov. 6, 2414 Cedarwood Drive.

• 4:57 a.m. Wednesday, Nov. 7, 1018 W. 24th St.

According to the fire reports, eight of the nine reported fires were at multi-unit apartment complexes, while one fire occurred in a trash receptacle. On five of the reports, “arson” is indicated.

In several of the cases, fire crews arrived to find materials such as papers on fire in hallways at the apartment complexes. None of the fires caused major damage, and there have not been any reported injuries as a result of the fires.
